OPA2335

最大漂移 0.05uV/℃ 的单电源 CMOS 运算放大器

The OPA334 and OPA335 series of CMOS operational amplifiers use auto-zeroing techniques to simultaneously provide very 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. Single or dual supplies as low as +2.7V ±1.35V and up to +5.5V ±2.75V may be used. These op amps are optimized for low-voltage, single-supply operation.

The OPA334 family includes a shutdown mode. Under logic control, the amplifiers can be switched from normal operation to a standby current of 2µA. When the Enable pin is connected high, the amplifier is active. Connecting Enable low disables the amplifier, and places the output in a high impedance state.

The OPA334 single version with shutdown comes in _Micro_SIZE SOT23-6. The OPA335 single version without shutdown is available in SOT23-5, and SO-8. The OPA2334 dual version with shutdown comes in _Micro_SIZE MSOP-10. The 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.
