These simple high-current sinks require the load to float between
the power supply and the sink.
In these circuits, OP77’s high gain, high CMRR, and low TCVOS
ensure high accuracy.

Figure 13. High Stability Voltage Reference
This simple bootstrapped voltage reference provides a precise 10 V
virtually independent of changes in power supply voltage, ambi-
ent temperature and output loading. Correct Zener operating
current of exactly 2 mA is maintained by R1, a selected 5 ppm/
∞C
resistor, connected to the regulated output. Accuracy is prima-
rily determined by three factors: the 5 ppm/
∞C temperature
coefficient of D1, 1 ppm/
∞C ratio tracking of R2 and R3, and
operational amplifier VOS errors.
VOs errors, amplified by 1.6 (AVCL), appear at the output and
can be significant with most monolithic amplifiers. For example,
an ordinary amplifier with TCVOS of 5
mV/∞C contributes 0.8 ppm/
∞C of output error while the OP77, with TCVOS of 0.3 mV/∞C,
contributes but 0.05 ppm/
∞C of output error, thus effectively
eliminating TCVOS as an error consideration.
The high gain and low TCVOS assure accurate operation with
inputs from microvolts to volts. In this circuit, the signal always

The high gain and low TCVOS assure accurate operation with
inputs from microvolts to volts. In this circuit, the signal always
appears as a common-mode signal to the op amps. The OP77E
CMRR of 1
V/V assures errors of less than 2 ppm.
