OPA2735AIDGKTG4

运算放大器 - 运放 0.05uV/degC single- supply CMOS

DESCRIPON

The OPA734 and OPA735 series of CMOS operational amplifiers use auto-zeroing techniques to simultaneously provide low offset voltage 5µV max and near-zero drift over time and temperature. These miniature, high-precision, low quiescent current amplifiers offer high input impedance and rail-to-rail output swing within 50mV of the rails. Either single or bipolar supplies can be used in the range of +2.7V to +12V ±1.35V to ±6V. They are optimized for low-voltage, single-supply operation.

The OPA734 family includes a shutdown mode. Under logic control, the amplifiers can be switched from normal operation to a standby current that is 9µA max and the output placed in a high-impedance state.

The single version is available in the MicroSIZE SOT23-5 SOT23-6 for shutdown version and the SO-8 packages. The dual version is available in the MSOP-8 and SO-8 packages MSOP-10 only for the shutdown version. All versions are specified for operation from −40°C to +85°C.
