Zer -Drift Series FEATURES DESCRIPTION. LOW OFFSET VOLTAGE: 5 V (max) The OPA334 and OPA335 series of CMOS operational amplifiers use auto-zeroing techniques to simultaneously ZERO DRIFT: V/ C (max). provide very low offset voltage (5 V max), and near-zero drift QUIESCENT CURRENT: 285 A over time and temperature. These miniature, high-precision, SINGLE-SUPPLY OPERATION low quiescent current amplifiers offer high input impedance and rail-to-rail output swing. Single or dual supplies as low as SINGLE AND DUAL VERSIONS. + ( ) and up to + ( ) may be used. SHUTDOWN These op amps are optimized for low-voltage, SINGLE-SUPPLY MicroSIZE PACKAGES operation. The OPA334 family includes a shutdown mode. Under logic control, the amplifiers can be switched from normal operation APPLICATIONS to a standby current of 2 A.

2 When the Enable pin is con- TRANSDUCER APPLICATIONS nected high, the amplifier is active. Connecting Enable low disables the amplifier, and places the output in a high- TEMPERATURE MEASUREMENT impedance state. ELECTRONIC SCALES The OPA334 (single version with shutdown) comes in MEDICAL INSTRUMENTATION MicroSIZE SOT23-6. The OPA335 (single version without BATTERY-POWERED INSTRUMENTS shutdown) is available in SOT23-5, and SO-8. The OPA2334 . (dual version with shutdown) comes in MicroSIZE MSOP-10. HANDHELD TEST EQUIPMENT The OPA2335 (dual version without shutdown) is offered in the MSOP-8 and SO-8 packages. All versions are specified for operation from 40 C to +125 C.
