Product details
Overview
ADA4062-4ACPZ-R7 from Analog Devices is a quad JFET-input operational amplifier optimized for low-power, high-precision signal conditioning in industrial and instrumentation systems. It delivers 50 pA maximum input bias current, 165 μA typical supply current per amplifier, ±15 V dual-supply operation, and 1.4 MHz gain bandwidth - enabling precision buffering and active filtering in battery-powered or thermally constrained designs.
For engineers reviewing the ADA4062-4ACPZ-R7 datasheet, ADA4062-4ACPZ-R7 pinout, ADA4062-4ACPZ-R7 application, or ADA4062-4ACPZ-R7 equivalent, key selection criteria include ultralow input bias current for high-impedance sensor interfacing, rail-to-rail output swing capability (±13.5 V/±13.8 V), extended −40°C to +125°C operating range, and 16-lead LFCSP package thermal performance.
Technical Context
The ADA4062-4ACPZ-R7 implements a JFET-input front-end with 10 TΩ typical input resistance and 5 μV/°C offset voltage drift, supporting stable DC-coupled amplification across temperature. Its unity-gain stable architecture and 78° phase margin ensure robust closed-loop behavior in gain-of-1 configurations without external compensation.
Designed for dual-supply operation from ±5 V to ±15 V, it maintains 90 dB typical CMRR and 83 dB large-signal voltage gain while delivering 3.3 V/μs slew rate and 3.5 μs settling time to 0.1% - balancing speed, precision, and power efficiency in multichannel analog signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad JFET-input op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8643ARUZ | CMOS input (not JFET); 1 pA bias current; 36 V supply max; 24 MHz GBP | Better speed and lower bias current but higher supply current (1.2 mA/amp) and no extended temp rating | Select AD8643ARUZ only when bandwidth >10 MHz is required and power budget allows 4.8 mA total quiescent current |
| TL074CDR | Bipolar JFET input; 200 pA bias current; 3 mA supply current; −40°C to +85°C rating | Lower cost but 12× higher supply current and limited temperature range | Choose TL074CDR for commercial-grade, non-temperature-critical applications where cost dominates power/performance trade-offs |
Compared with AD8643ARUZ and TL074CDR, ADA4062-4ACPZ-R7 uniquely balances ultralow power (660 μA total), extended temperature operation, and JFET-input precision - making it optimal for battery-powered industrial sensors and medical devices requiring long-term DC stability.

FAQ
What is the maximum supply voltage for ADA4062-4ACPZ-R7?
The ADA4062-4ACPZ-R7 supports dual-supply operation from ±5 V to ±15 V, with absolute maximum ratings of ±18 V on both V+ and V– pins. Operation beyond ±15 V is not recommended due to increased power dissipation and potential degradation of offset voltage drift performance.
Does ADA4062-4ACPZ-R7 require external compensation for unity-gain stability?
No, ADA4062-4ACPZ-R7 is internally compensated and unity-gain stable. Its 78° phase margin at AV = 1 ensures stable operation without external capacitors or feedback network adjustments, simplifying design in buffer and gain-of-1 configurations.
How is the exposed thermal pad on ADA4062-4ACPZ-R7 configured?
The exposed pad on ADA4062-4ACPZ-R7 must be soldered to a PCB copper plane connected to V– (pin 16). This connection is mandatory for both thermal performance (θJC = 12°C/W) and electrical integrity, as specified in datasheet Figure 4 and Note 2.
Can ADA4062-4ACPZ-R7 operate with single-supply configurations?
ADA4062-4ACPZ-R7 is specified for dual-supply operation but can function in single-supply mode if the input common-mode range (−11.5 V to +15 V relative to V–) and output swing (to within 1.2 V of rails) are respected. For true single-supply use, a reference voltage must be applied to the non-inverting inputs to establish proper DC operating point.
What is the guaranteed minimum channel separation for ADA4062-4ACPZ-R7?
ADA4062-4ACPZ-R7 guarantees 130 dB channel separation at 1 kHz, measured under standard conditions (VSY = ±15 V, VIN = 10 V p-p, RL = 10 kΩ). This value reflects worst-case crosstalk between any two amplifier sections in the quad package and is validated across the full −40°C to +125°C temperature range.
