In precision signal chain design, it is often difficult to achieve both low power consumption and high accuracy. ADI’s ADA4062-4 four-channel JFET-input operational amplifier, with its ultra-low bias current, low offset voltage and a supply current of just 165 μA per channel, offers an ideal solution for multi-channel systems that balances performance and power consumption. Mingjiada currently stocks genuine, in-stock units; please feel free to enquire and place your order.
ADA4062-4 Product Overview
The ADA4062-4 is a four-channel JFET-input operational amplifier from ADI, part of the ADA4062 series (the dual-channel variant is the ADA4062-2). This series is renowned for its industry-leading performance, excelling in low power consumption, low offset voltage, low drift and ultra-low bias current.
With a supply current as low as 165 μA (typical) per amplifier, whilst maintaining a slew rate of 3.3 V/μs and a gain-bandwidth product of 1.4 MHz, it is particularly well-suited to low-power applications such as portable devices, battery-powered instruments and high-density channel boards. The ADA4062-4 is rated for an extended industrial temperature range of −40°C to +125°C, enabling it to withstand harsh industrial environments.

ADA4062-4 Key Features
Ultra-low input bias current
The ADA4062-4 utilises a JFET input stage design, with a maximum input bias current of just 50 pA (typically 2 pA). This feature makes it an ideal choice for bias-current-sensitive applications such as high-impedance sensor interfaces, photodiode amplification and integrators.
Balance of low power consumption and high performance
A quiescent current of 165 μA per channel significantly reduces the total power consumption of multi-channel systems, whilst a slew rate of 3.3 V/μs and a gain-bandwidth product of 1.4 MHz are sufficient to cover most industrial signal conditioning requirements.
Excellent DC Accuracy
A typical offset voltage temperature drift of 4 μV/°C and a typical common-mode rejection ratio (CMRR) of 90 dB ensure stable measurement accuracy over a wide temperature range and in the presence of varying common-mode voltages.
Unit-Gain Stability
The device is unit-gain stable, facilitating its use in various feedback configurations without the need for additional compensation networks.
Typical Applications
Thanks to its combination of low power consumption, high input impedance and low bias current, the ADA4062-4 is widely used in the following fields:
Industrial process control: sensor signal conditioning, transmitter interfacing
Instrumentation: precision measurement, data acquisition systems
Active filters: low-power multi-channel filter designs
Data conversion: ADC/DAC buffering and driving
Power control and monitoring: current sensing, voltage monitoring
Integrator circuits: charge amplification, time integration
Input buffering: high-impedance signal source isolation buffering
