DESCRIPTION

The INA137 and INA2137 are differential line receivers

consisting of high performance op amps with on-chip

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 INA137 and INA2137 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 INA137 is available in 8-pin DIP and SO-8

surface-mount packages. The INA2137 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.
