DESCRIPTION
OPA336 series microPower CMOS operational amplifiers are designed for battery-powered applications.
They operate on a single supply with operation as low as 2.1V.
The output is rail-to-rail and swings to within 3mV of the supplies with a 100kW load.
The common-mode range extends to the negative supply—ideal for single-supply
applications.
Single, dual, and quad versions have identical specifications for maximum design flexibility.
In addition to small size and low quiescent current (20mA/amplifier), they feature low offset voltage (125mV max), low input bias current (1pA), and high openloop gain (115dB).
Dual and quad designs feature completely independent circuitry for lowest crosstalk and freedom from interaction.
OPA336 packages are the tiny SOT23-5 surface mount and SO-8 surface-mount.
OPA2336 come in the miniature MSOP-8 surface-mount, SO-8 surface-mount, and DIP-8 packages.
The OPA4336 package is the space-saving SSOP-16 surface-mount.
All are specified from –40°C to +85°C and operate from –55°C to +125°C.

DESCRIPTION
The ADS7884 is a 10-bit, 3-MSPS analog-to-digital converter (ADC), and the ADS7885 is a 8-bit, 3-MSPS ADC.
The devices include a capacitor based SAR A/D converter with inherent sample and hold.
The serial interface in each device is controlled by the CS and SCLK signals for glueless connections with microprocessors and DSPs.
The input signal is sampled with the falling edge of CS, and SCLK is used for conversion and serial data output.
The devices operate from a wide supply range from 2.7V to 5.5V.
The low power consumption of the devices make them suitable for battery-powered applications.
The devices also include a power saving powerdown feature for when the devices are operated at lower conversion speeds.
The high level of the digital input to the device is not limited to device VDD.
This means the digital input can go as high as 5.5V when device supply is 2.7V.
This feature is useful when digital signals are coming from other circuit with different supply levels.
Also this relaxes restriction on power up sequencing.
The ADS7884 and ADS7885 are available in a 6-pin SOT23 package and are specified for operation from –40°C to 125°C.

DESCRIPTION
The OPA2830 is a dual, low-power, single-supply, wideband, voltage-feedback amplifier designed to operate on a single +3V or +5V supply. Operation on ±5V or +10V supplies is also supported. The input range extends below ground and to within 1.8V of the positive supply. Using complementary common-emitter outputs provides an output swing to within 25mV of ground and +VS while driving 150W.
High output drive current (75mA) and low differential gain and phase errors also make it ideal for single-supply consumer video products.
Low distortion operation is ensured by the high gain bandwidth product (100MHz) and slew rate (500V/μs), making the OPA2830 an ideal input buffer stage to 3V and 5V CMOS Analog-to-Digital Converters (ADCs). Unlike earlier low-power, single-supply amplifiers, distortion performance improves as the signal swing is decreased. A low 9.2nV/ÖHz input voltage noise supports wide dynamic range operation.
The OPA2830 is available in an industry-standard SO-8 package. The OPA2830 is also available in a small MSOP-8 package. For fixed-gain and line driver applications, consider the OPA2832.

DESCRIPTION
The BUF01900 and BUF01901 provide a programmable voltage output with 10-bit resolution. Programming of the output occurs through an industry-standard, two-wire serial interface. Once the correct VCOM voltage is established it can easily be stored into the integrated nonvolatile memory.
An initial output voltage and adjustment range can be set by an external resistor-divider. With its large output current capability (up to 100mA), the BUF01900 and BUF01901 are ideally suited as programmable VCOM calibrators in LCD panels.
The BUF01901 has the digital-to-analog converter (DAC) output brought out directly. It has a slightly lower cost than the BUF01900, and works very well with the integrated VCOM in traditional gamma buffers such as the BUFxx702, BUFxx703, BUFxx704 and BUF11705.
The BUF01900 and BUF01901 are both available in TSSOP-8 and 3mm x 3mm DFN-10 packages. The DFN-10 package (only 0.9mm in height) is especially well-suited for notebook computers. Both devices are specified from −40°C to +85°C.

The DAC8881 requires an external reference voltage to set the output range of the DAC channel. A programmable power-on reset circuit is also incorporated into the device to ensure that the DAC output powers up at zero-scale or midscale, and remains there until a valid write command.
Additionally, the device has the capability to function in either unipolar straight binary or 2's complement mode. The DAC8881 provides a power-down feature. accessed over thePDN pin, that reduces the current consumption to 25μA at 5V. Power consumption is 6mW at 5V, reducing to 125μW in power-down mode.
The DAC8881 is available in a 4x4mm QFN-24 package with a specified operating temperature range of –40°C to +105°C.

DESCRIPTION
The ADS1174 (quad) and ADS1178 (octal) are multiple delta-sigma (ΔΣ) analog-to-digital converters (ADCs) with data rates up to 52k samples-per-second (SPS), which allow synchronous sampling of four and eight channels. These devices use identical packages, permitting drop-in expandability.
The delta-sigma architecture offers near ideal 16-bit lainceapreitryf)ormcoamncbeine(d97wdBithS0N.0R0,5d–B105pdaBssbTaHnDd, r1ipLpSleB, and linear phase response.
The high-order, chopper- stabilized modulator achieves very low drift (4μV/°C offset, 4ppm/°C gain) and low noise (1LSBPP). The on-chip finite impulse response (FIR) filter provides a usable signal bandwidth up to 90% of the Nyquist rate with 100dB of stop band attenuation while suppressing modulator and signal out-of-band noise.
Two operating modes allow for optimization of speed and power: High-speed mode (32mW/Ch at 52kSPS), and Low-power mode (8mW/Ch at 10kSPS).
A SYNC input control pin allows the device conversions to be started and synchronized to an
external event. SPI and Frame-Sync serial interfaces are supported. The device is fully specified over the extended industrial range (–40°C to +105°C) and is available in an HTQFP-64 PowerPAD™ package.
