AS1713

Difference Amplifier, 10MHz, 10V/µs, Rail-to-Rail I/O

with Shutdown

1 General Description

2 Key Features

ꢀ

Constant Output Drive Capability: 50mA

The AS1713 is a low cost cmos difference amplifier pro-

viding extended common mode voltage range for a sin-

gle rail 5V supply. Resistor trimming during final test

ensures a typical common mode 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 sup-

port for a number of signal processing applications such

as audio line receivers, ground loop breakers and cur-

rent sensing. Linearity is suitable for 12bit ADC mea-

surement.

Rail-to-Rail Input and Output

Supply Current: 1.6mA

Single-Supply Operation: 2.7 to 5.5V

Voltage Gain: 1

Gain-Bandwidth Product: 10MHz

High Slew Rate: 10V/µs

Power-Supply Rejection Ratio: -70dB

Common Mode Rejection Ratio: -60dB

No Phase Reversal for Overdriven Inputs

A classical single amplifier approach ensures that the

differential gain is determined by a simple ratio of two

internal resistors. A fixed gain of x1 is available.

Unity-Gain Stable for Capacitive Loads: Up to 100pF

Shutdown Mode Current: 1nA

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

at each input terminal. This feature provides additional

common mode rejection when long balanced input

cables connect at the input.

MLPD (2x2mm) 8-pin package

A EN pin reduces the quiescent current of the device.

3 Applications

The device is ideal for headphone amplifiers with ground

interference rejection, infotainment high drive audio line

buffers with ground interference rejection, audio differ-

ential-to-single-ended conversion and instrumentation

amplifier back-end.
