1 General Description

2 Key Features

The AS1713 is a low cost cmos difference amplifier providing

extended common mode voltage range for a single rail 5V supply.

Resistor trimming during final test ensures a typical common mode

lid rejection of 60dB. Low input bias currents, 10MHz gain bandwidth,

low total harmonic distortion (THD) and a rail-to-rail output drive

capability of typically 200mA (@ 5V supply) provide support for a

number of signal processing applications such as audio line receiv-

a ers, ground loop breakers and current sensing. Linearity is suitable

for 12bit ADC measurement.

v A classical single amplifier approach ensures that the differential

ill gain is determined by a simple ratio of two internal resistors. A fixed

gain of x1 is available.

Single ended input resistance is equalised (10kΩ ±20%) at each

t input terminal. This feature provides additional common mode rejec-

tion when long balanced input cables connect at the input.

G s A EN pin reduces the quiescent current of the device.
