The DIO2051ST5 is a single rail-to-rail low power operational amplifier (op amp) with a very low power consumption of only 350 µA. It is manufactured by Dioo, a company which specializes in designing and manufacturing high-performance analog semiconductor components. The op amp features a wide range of inputs for applications ranging from high-impedance, high-sensitivity, low-power, and audio to video signal conditioning. It provides an output current of 40 mA and an input voltage range of 1.8 V to 5 V. The output can be configured for either rail-to-rail operation or single-ended (unipolar) operation with a rail-to-rail output swing. The device is fully characterized for operation over the full temperature range from -40°C to +125°C. The op amp also provides excellent op amp specs, including very high open-loop gain (100 dB min) and low offset voltage (8 mV). It is also unity-gain stable with a high unity-gain bandwidth of 2 MHz. The amplifier has a total gain bandwidth product (GBP) of 8 MHz and a slew rate of 6 V/µs. Overall, the DIO2051ST5 is an ideal op amp for low-power, high-impedance applications where accuracy, high gain, and low power consumption are critical.
