The INA134 and INA2134 are differential line receiv-
ers consisting of high performance op amps with on-
chip precision resistors. They are fully specified for
high performance audio applications and have excel-
lent ac specifications, including low distortion
(0.0005% at 1kHz) and high slew rate (14V/
μ
s), assur-
ing 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.
