Output voltage of the adjustable versions is set with two external resistors. The REG1117 low dropout voltage allows its use with as little as 1V input-output voltage differential.
Laser trimming assures excellent output voltage accuracy without adjustment. An NPN output stage allows output stage drive to contribute to the load current for maximum efficiency.

DESCRIPTION
The BUF08800 reference generator offers eight programmable reference channels that can be used depending on the application needs. For example, all eight channels can be used for gamma correction, or some as gamma references and some to digitally adjust the gate voltages
or VCOM.
All gamma/VCOM channels swing to within 100mV of the positive or negative supply rail with a 10mA load. All channels are programmed using a standard two-wire interface that supports standard operation up to 400kHz and also high-speed data transfer up to 3.4MHz.
The integrated VCOM driver features up to 400mA peak current drive. VCOM voltage compensation at different locations on the LCD panel can be accomplished using the negative input of the integrated VCOM op amp.
The Gate High and Low voltages can differ because of changes in panel size or technology. The BUF08800 supports digital adjustment circuits for the gate voltages.
This feature enables the adjustment of gate voltages through software without changing hardware, thus reducing development time and risk.
The BUF08800 is manufactured using Texas Instruments’ proprietary, state-of-the-art, high-voltage CMOS process.
This process allows very dense logic as well as high supply voltage operation of up to 22V.
The BUF08800 is available in a small TSSOP-20 PowerPad package, and is specified from −40°C to +85°C

DESCRIPTION
 The REG710 is a switched capacitor voltage converter, that produces a regulated, low-ripple output voltage from an unregulated input voltage. A wide-input supply voltage of 1.8V to 5.5V makes the REG710 ideal for a variety of battery sources, such as single cell Li-Ion, or two and three cell nickel- or alkaline-based chemistries.
 The input voltage may vary above and below the output voltage and the output will remain in regulation. It works equally well for step-up or step-down applications without the need for an inductor, providing low EMI DC/DC conversion. The high switching frequency allows the use
of small surface-mount capacitors, saving board space and reducing cost. The REG710 is thermally protected and current limited, protecting the load and the regulator during fault conditions.
 Typical ground pin current (quiescent current) is 65μA with no load, and less than 1μA in shutdown mode. The 5.5V version of the REG710 is available in a thin TSOT23-6 package. All other versions are available in a small SOT23-6 package.

DESCRIPTION
 The OPA890 represents a major step forward in unity-gain stable, voltage-feedback op amps. A new internal architecture provides slew rate and full-power bandwidth previously found only in wideband, current-feedback op amps. These capabilities provide exceptional full power bandwidth.
 Using a single +5V supply, the OPA890 can deliver a 1V to 4V output swing with over 35mA drive current and 220MHz bandwidth. This combination of features makes the OPA890 an ideal RGB line driver or single-supply analog-to-digital converter (ADC) input driver.
 The low 1.1mA supply current of the OPA890 is precisely trimmed at +25°C. This trim, along with low temperature drift, ensures lower maximum supply current than competing products. System power may be reduced further using the optional disable control pin. Leaving this disable pin open, or holding it HIGH, operates the OPA890 normally. If pulled LOW, the OPA890 supply current drops to less than 30mA while the output goes into a high-impedance state.

DESCRIPTION
 The ADS5231 is a dual, high-speed, high dynamic range, 12-bit pipelined analog-to-digital converter (ADC). This converter includes a high-bandwidth sample-and-hold amplifier that gives excellent spurious performance up to and beyond the Nyquist rate. The differential nature of the sample-and-hold amplifier and ADC circuitry minimizes even-order harmonics and gives excellent common-mode noise immunity.

 The ADS5231 provides for setting the full-scale range of the converter without any external reference circuitry. The internal reference can be disabled, allowing low-drive, external references to be used for improved tracking in multichannel systems. The ADS5231 provides an over-range indicator flag to indicate an input signal that exceeds the full-scale input range of the converter. This flag can be used to reduce the gain of front-end gain control circuitry.
There is also an output enable pin to allow for multiplexing and testing on a printed circuit board (PCB).

 The ADS5231 employs digital error correction techniques to provide excellent differential linearity for demanding imaging applications. The ADS5231 is available in a TQFP-64 package.
