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/µs), 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 ver-
sion features completely independent circuitry for low-
est 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.
