Data Sheet OP200 DUAL 12-BIT VOLTAGE OUTPUT DAC DUAL PRECISION VOLTAGE REFERENCE
The dual output DAC shown in Figure 33 is capable of providing A dual OP200 and a REF43, a 2.5 V reference, can be used to untrimmed 12-bit accurate operation over the entire military build a ±2.5 V precision voltage reference. Maximum output temperature range. Offset voltage, bias current, and gain errors current from each reference is ±10 mA with load regulation of the OP200 contribute less than 1/10 of an LSB error at 12 bits under 25 μV/mA. Line regulation is better than 15 μV/V and over the military temperature range. output voltage drift is under 20 μV/°C. Output voltage noise from 0.1 Hz to 10 Hz is typically 75 μV p-p. R1 and D1 ensure correct startup.
