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.
