DAC8800

The DAC-8800 is a kind of octal 8-bit CMOS D/A converter. It is designed to be a general purpose digitally controlled voltage adjustment device. The output voltage range can be independently set for each set of four D/A converters. In addition, both unipolar and bipolar output voltage ranges are easy to establish by external reference input high and low terminals. The digitally-programmed output voltages are ideal for op amp trimming, voltage-controlled amplifier gain setting and any general purpose trimming tasks. The typical applications include voltage set point control, digital offset & gain adjustment, microprocessor controlled calibration and general purpose trimming adjustments.

There are some features of DAC8800 as follows: (1)±1/2 LSB total unadjusted error; (2)2s setting time; (3)serial data input; (4)±full-scale output set by VREFH and VREFL; (5)unipolar and bipolar operation; (6)TTL input compatible; (7)20-pin DIP or SOL package; (8)low cost.

The following is about the absolute maximum ratings of DAC8800(TA=+25): (1)VDD to VSS: 0 to +20 V; (2)VDD to GND: 0 to +20 V; (3)VSS to GND: -20 to 0 V; (4)digital input voltage to GND: GND-0.3 to VDD+0.3 V; (5)VREFH to GND: VREFL to VDD V; (6)VREFL to GND: VSS to VREFH V; (7)VOUT to GND: VREFL to VREFH V; (8)operating temperature range: military, DAC-8800BR: -55 to +125; extended industrial, DAC-8800FR, FP, FS: -40 to +85; (9)maximum junction temperature (Tj Max): +150; (10)storage temperature: -65 to 150; (11)lead temperature (soldering, 10secs): +300.
