1 / 9 page ©1997 Burr-Brown Corporation PDS-1391B Printed in U.S.A. July, 1997 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/ 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. ® FEATURES q SINGLE AND DUAL VERSIONS q LOW DISTORTION: 0.0005% at f = 1kHz q HIGH SLEW RATE: 14V/ µs q FAST SETTLING TIME: 3 µs to 0.01% q WIDE SUPPLY RANGE: ±4V to ±18V q LOW QUIESCENT CURRENT: 2.9mA max q HIGH CMRR: 90dB q FIXED GAIN = ±6dB q PACKAGES—SINGLE: 8-PIN DIP, SO-8 DUAL: 14-PIN DIP, SO-14 APPLICATIONS q AUDIO DIFFERENTIAL LINE RECEIVER q G = 1/2 OR G = 2 AMPLIFIER q INSTRUMENTATION BUILDING BLOCK q CURRENT SHUNT MONITOR q VOLTAGE-CONTROLLED CURRENT SOURCE q GROUND LOOP ELIMINATOR INA137 INA2137 AUDIO DIFFERENTIAL LINE RECEIVERS ±6dB (G = 1/2 or 2) International Airport Industrial Park • Mailing Address: PO Box 11400, Tucson, AZ 85734 • Street Address: 6730 S.
