GENERAL DESCRIPTION
The XRD87L99 is a flexible, easy to use, precision 10-bit analog-to-digital converter with 8-channel mux that operates over a wide range of input and sampling conditions. The XRD87L99 can operate with pulsed "on demand" conversion operation or continuous "pipeline" operation for sampling rates up to 2MHz. The elimination of the S/H requirements, very low power, and small package size offer the designer a low cost solution. No sample and hold is required for CCD applications up to 2MHz, or multiplexed input applications when the signal source bandwidth is limited to 100kHz. The input architecture of the XRD87L99 allows direct interface to any analog input range between AGND and AVDD. The user simply sets VREF(+) and VREF(-) to encompass the desired input range.
Scaled reference resistor taps @ 1/4 R, 1/2 R and 3/4 R allow for customizing the transfer curve as well as providing a 1/2 span reference voltage. Digital outputs are CMOS and TTL compatible.
The XRD87L99 uses a two-step flash technique. The first segment converts the 5 MSBs and consists of autobalanced comparators, latches, an encoder, and buffer storage registers. The second segment converts the remaining 5 LSBs.
When the power down input is "high", the data outputs DB9 to DB0 hold the current values and VREF(-) is disconnected from VREF1(-). The power consumption during the power down mode is 0.1mW.

GENERAL DESCRIPTION
The XRP7604 is a non-synchronous voltage mode PWM step down converter with integrated high side FET optimized to drive high power LEDs at up to 1A of continuous current. A wide 4.5V to 29V input voltage range allows for single supply operations from industry standard 5V, 12V or 24V power rails.

GENERAL DESCRIPTION
The XR-8038A is a precision waveform generator IC capable of producing sine, square, triangular, sawtooth, and pulse waveforms, with a minimum number of external components and adjustments. The 8038A allows the elimination of the external distortion adjusting resistor which greatly improves the temperature drift of distortion, as well as lowering external parts count. Its operating frequency can be selected over eight decades of frequency, from 0.001Hz to 200KHz, by the choice of external R-C components. The frequency of oscillation is highly stable over a wide range of temperature and supply voltage changes. Both full frequency sweeping as well as smaller frequency variations (FM) can be accomplished with an external control voltage. Each of the three basic waveform outputs, (i.e., sine, triangle and square) are simultaneously available from independent output terminals.
The XR-8038A monolithic waveform generator uses advanced processing technology and Schottky-barrier diodes to enhance its frequency performance. It can be readily interfaced with a monolithic phase-detector circuit, such as the XR-2228 to form stable phase-locked circuits.

FEATURES
*Low Frequency Drift 50ppm/°C, Typical
