• INPUT BIAS CURRENT: 15pA

• INPUT OFFSET VOLTAGE: 150µV (max)

operates over a wide supply voltage range, ±4V to

±18V on a low supply current (4.8mA/Ch, typ).

• INPUT OFFSET DRIFT: 1.5µV/°C

• GAIN BANDWIDTH: 22MHz

Excellent ac characteristics, such as a 22MHz gain

bandwidth product (GBW), a slew rate of 28V/

µs, and

well-suited for a wide range of applications including

• WIDE SUPPLY RANGE: ±4V to ±18V

16-bit to 18-bit mixed signal systems, transimpedance

(I/V-conversion) amplifiers, filters, precision ±10V

front ends, and professional audio applications.
