DESCRIPTION

The INA134 and INA2134 are differential line receivers

consisting of high performance op amps with onchip

precision resistors. They are fully specified for

high performance audio applications and have excellent

ac specifications, including low distortion

(0.0005% at 1kHz) and high slew rate (14V/ms), assuring

good dynamic response. In addition, wide output

voltage swing and high output drive capability allow

use in a wide variety of demanding applications. The

dual version features completely independent circuitry

for lowest crosstalk and freedom from interaction,

even when overdriven or overloaded.

The INA134 and INA2134 on-chip resistors are laser

trimmed for accurate gain and optimum

common-mode rejection. Furthermore, excellent TCR

tracking of the resistors maintains gain accuracy and

common-mode rejection over temperature. Operation

is guaranteed from ±4V to ±18V (8V to 36V total

supply).

The INA134 is available in 8-pin DIP and SO-8

surface-mount packages. The INA2134 comes in

14-pin DIP and SO-14 surface-mount packages. Both

are specified for operation over the extended industrial

temperature range, –40°C to +85°C.
