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 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. 6 Output 3 12kΩ 6kΩ 1 +In Ref INA137 4 V– 2 12kΩ V+ 11 6kΩ –In A 12 Sense A A 13 Out A +In A 3 12kΩ 6kΩ 14 Ref A –In B 6 12kΩ 6kΩ 10 Sense B B 9 Out B +In B 5 12kΩ 6kΩ 8 Ref B INA2137 4 V– International Airport Industrial Park • Mailing Address: PO Box 11400, Tucson, AZ 85734 • Street Address: 6730 S.
