AC ELECTRICAL CHARACTERISTICS

(VDD = 3V, GND = 0, RL = 10kΩ connected to 1.5V, CL = 20pF, CIN = 30pF connected to GND, VIN = 0, TA = TMIN to TMAX, unless

otherwise noted. Typical values are at TA = +25°C.)

Note 2: All specifications are 100% tested at TA = +25°C, temperature limits are guaranteed by design.

Note 3: Guaranteed by design. Not production tested.

Note 4: PSRR is input-referred.

Note 5: Noise measurement includes the noise contribution of the internal gain-setting resistors.
