ELECTRICAL CHARACTERISTICS: VS = +5V

Boldface limits apply over the specified temperature range, TA = −40°C to +125°C.

At TA = +25°C, RL = 10kΩ connected to VS/2, REF pin 1 connected to ground, and REF pin 2 connected to VREF = 5V, unless otherwise noted.

(1) Includes effects of amplifier input bias and offset currents.

(2) Reference divider accuracy specifies the match between the reference divider resistors using the configuration in Figure 2.

(3) Internal resistors are ratio matched but have ±20% absolute value.

(4) Includes effects of amplifier input current noise and thermal noise contribution of resistor network.
