Shenzhen Mingjiada Electronics Co., Ltd. has the ADI (Analog Devices) ADA4692-2ACPZ dual-channel operational amplifier in stock. This device is a low-power, low-noise, rail-to-rail output general-purpose operational amplifier with a gain-bandwidth product of 3.6 MHz and a slew rate of 1.3 V/µs. With a quiescent current of only 180 µA per channel and housed in a 2 mm × 2 mm ultra-compact LFCSP package, it is an ideal choice for applications such as portable devices, sensor signal conditioning, and audio processing.
Product Overview: High-Precision, Low-Power Dual-Channel Op-Amp
The ADA4692-2ACPZ is a dual-channel, voltage-feedback operational amplifier from Analog Devices, Inc. (ADI), designed specifically for applications requiring an optimal balance between power consumption and performance.
The device supports single-supply voltages from 2.7 V to 5.5 V or dual-supply voltages from ±1.35 V to ±2.5 V. With rail-to-rail output capability, it fully utilizes the supply voltage range to provide greater output dynamic range. Its typical input bias current of 0.5 pA and input offset voltage of 500 µV ensure high-precision signal amplification, making it particularly suitable for connecting to high-impedance sensors.

Key Features and Functional Advantages
1. Ultra-low power consumption extends battery life
The ADA4692-2ACPZ consumes only 180 µA of typical quiescent current per channel, with power consumption far lower than that of traditional operational amplifiers. Combined with its minimum operating voltage of 2.7 V, it is ideally suited for power-sensitive applications such as battery-powered portable medical devices, consumer audio players, and wireless communication terminals.
2. Extremely Low Input Bias Current, Suitable for High-Impedance Sensors
An extremely low input bias current of 0.5 pA is one of the device’s key advantages. This feature enables it to accurately amplify weak current signals from high-impedance sources such as photodiodes and piezoelectric sensors, delivering outstanding performance in applications such as photodiode amplifiers and charge amplifiers.
3. Rail-to-Rail Output for Maximized Dynamic Range
The device supports rail-to-rail output, with an output voltage swing that extends close to the power supply rails. This effectively utilizes the limited power supply voltage range to provide a wider output dynamic range, making it particularly suitable for low-voltage single-supply systems.
4. Low Noise and Low Distortion Ensure Signal Fidelity
With a low voltage noise density of 16 nV/√Hz and low distortion of 0.003% THD+N, it maintains high-fidelity signal amplification within the audio frequency band. It significantly improves signal quality in portable audio players, active filters, and ADC driver circuits.
5. Wide Operating Temperature Range for Harsh Environments
Supporting an extended industrial-grade temperature range from -40°C to +125°C, it meets reliability requirements in harsh environments such as industrial control and automotive electronics.
