OPA335AIDBVR Datasheet

0.05μV/°c Max, Single-Supply Cmos Operational Amplifiers Zer?-Drift Series


The OPA335AIDBVR and OPA334 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 con- nected high, the amplifier is active. Connecting Enable low disables the amplifier, and places the output in a high- impedance state.
