Product details
Overview
ADA4610-2ACPZ-R7 from Analog Devices is a dual-channel, precision JFET-input operational amplifier with rail-to-rail output, 0.4 mV max offset voltage (B grade), 7.30 nV/√Hz voltage noise density at 1 kHz, and ±5 V to ±15 V dual-supply operation. It delivers low input bias current (5 pA typical), no phase reversal, and unity-gain stability-ideal for high-impedance photodiode amplification and precision shunt-based current measurement in medical instrumentation.
For engineers reviewing the ADA4610-2ACPZ-R7 datasheet, ADA4610-2ACPZ-R7 pinout, ADA4610-2ACPZ-R7 application, or ADA4610-2ACPZ-R7 equivalent, key selection criteria include verified rail-to-rail output swing under load, confirmed 2 µV/°C max offset drift (B grade), guaranteed 15.4 MHz gain bandwidth at ±5 V, and documented absence of input-phase reversal beyond common-mode range.
Technical Context
The ADA4610-2ACPZ-R7 implements a precision JFET input stage with >10¹³ Ω input resistance and differential input capacitance of 3.1 pF, enabling stable operation with high-source-impedance sensors. Its output stage supports rail-to-rail swing into 600 Ω loads while maintaining 0.00025% THD+N at 1 kHz.
It achieves 61° phase margin and 9.3 MHz unity-gain crossover with 2 kΩ load, ensuring robust stability in active filter and precision buffer configurations-even with capacitive loads up to 100 pF-without requiring external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Offset Voltage (B grade) | 0.4 mV max - enables sub-10 µV error in 100× gain precision current sensing at room temperature. |
| Voltage Noise Density | 7.30 nV/√Hz at 1 kHz - ensures minimal contribution to total system noise in low-frequency sensor interfaces. |
| Gain Bandwidth Product | 15.4 MHz at ±5 V - supports stable 10× closed-loop gain up to ~1.5 MHz for anti-aliasing filters. |
| Input Bias Current | 5 pA typical - preserves signal integrity in >1 GΩ source impedance applications like photodiode amps. |
| Common-Mode Rejection | 110 dB typical - rejects power supply ripple and shared-noise coupling in differential front-ends. |
| Supply Current per Amp | 1.70 mA typical - balances low-noise performance with moderate power budget in dual-channel systems. |
| Operating Temperature | −40°C to +125°C - qualified for industrial and automotive under-hood signal conditioning. |
Pinout & Package
ADA4610-2ACPZ-R7 is housed in an 8-lead LFCSP package (3 mm × 3 mm, 0.5 mm pitch) with exposed pad connected to V−. The package supports high thermal efficiency (θJC = 12°C/W) and compact PCB layout for space-constrained instrumentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output; rail-to-rail capable, drives ≥2 kΩ load to within 100 mV of rails. |
| 2 | −IN A | Inverting input for Channel A; high-impedance JFET node, 3.1 pF differential capacitance. |
| 3 | +IN A | Noninverting input for Channel A; matched to −IN A for optimal CMRR and offset performance. |
| 4 | V− | Negative supply rail; exposed pad must be soldered to this net for thermal and electrical integrity. |
| 5 | +IN B | Noninverting input for Channel B; electrically isolated but process-matched to Channel A inputs. |
| 6 | −IN B | Inverting input for Channel B; identical bias and noise characteristics as −IN A. |
| 7 | OUT B | Amplifier B output; independent channel with same AC/DC specs as OUT A. |
| 8 | V+ | Positive supply rail; supports ±5 V to ±15 V operation with 106 dB PSRR at DC. |
Key Features
| Feature | Design Value |
|---|---|
| No phase reversal | Guaranteed operation without output polarity inversion when inputs exceed ±VS, eliminating latch-up risk in overvoltage transients. |
| Rail-to-rail output | Swings to within 100 mV of V+ and V− at 2 kΩ load, maximizing dynamic range in single-supply or low-headroom systems. |
| Low long-term drift | 5 µV typical offset shift after 10,000 hours - critical for unattended medical monitoring and calibration-free test equipment. |
| High-speed settling | Stable with 100 pF capacitive load and fast transient response (≤10 µs to 0.1% for 4 V step) - suitable for multiplexed sensor arrays. |
| Ultra-low input current | 5 pA typical IB enables direct connection to >10 GΩ sources (e.g., piezoelectric sensors) without guard-ring circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision JFET op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8620ARMZ | Higher offset drift (10 µV/°C max), higher supply current (2.2 mA), no rail-to-rail output (1.2 V headroom). | Better suited for high-speed (>20 MHz) unity-gain buffers where output swing is less critical. | Choose AD8620ARMZ only if GBP >18 MHz is required and rail-to-rail output is unnecessary. |
| ADA4625-2ACPZ-R7 | Lower noise (4.2 nV/√Hz), faster slew rate (35 V/µs), but higher input bias current (20 pA) and narrower supply range (±4.5 V to ±15 V). | Preferred for audio line drivers and wideband photodetector amps where speed outweighs ultra-low IB. | Select ADA4625-2ACPZ-R7 when 10 MHz–100 MHz bandwidth and lower integrated noise dominate over femtoamp input current. |
Compared with AD8620ARMZ and ADA4625-2ACPZ-R7, the ADA4610-2ACPZ-R7 uniquely balances femtoamp input bias, rail-to-rail output, and sub-1 µV/°C drift-making it optimal for high-impedance, low-drift, wide-temperature applications where signal fidelity at DC and low frequencies is paramount.

FAQ
What is the maximum operating temperature range for the ADA4610-2ACPZ-R7?
The ADA4610-2ACPZ-R7 is specified over the −40°C to +125°C extended industrial temperature range. This rating is validated across all electrical parameters including offset voltage, drift, CMRR, and output drive capability-ensuring reliable operation in automotive engine control units, industrial PLC modules, and outdoor medical analyzers where ambient temperatures exceed 85°C.
Does the ADA4610-2ACPZ-R7 require external compensation for unity-gain stability?
No, the ADA4610-2ACPZ-R7 is unity-gain stable without external compensation. Its internal compensation ensures 61° phase margin at unity gain with 2 kΩ load, and it remains stable driving up to 100 pF capacitive loads-critical for direct connection to ADC input capacitors or long PCB traces in data acquisition systems using the ADA4610-2ACPZ-R7.
How does the exposed pad on the ADA4610-2ACPZ-R7 LFCSP package function electrically?
The exposed pad on the ADA4610-2ACPZ-R7 must be connected to the V− supply rail. It serves as both a low-thermal-resistance path (θJC = 12°C/W) and an electrical extension of the negative supply plane-reducing junction temperature rise by up to 35°C at full load and minimizing ground bounce in dual-amplifier switching scenarios involving the ADA4610-2ACPZ-R7.
Can the ADA4610-2ACPZ-R7 be used with single-supply operation?
Yes, the ADA4610-2ACPZ-R7 supports single-supply operation with input common-mode range extending to V− and rail-to-rail output swing. When operated from +10 V and GND, its inputs accept signals down to GND, and outputs swing from near-GND to within 100 mV of +10 V-enabling true single-supply designs such as battery-powered pH meters and portable gas sensors using the ADA4610-2ACPZ-R7.
What is the guaranteed maximum input offset voltage drift for the ADA4610-2ACPZ-R7?
The ADA4610-2ACPZ-R7 B grade guarantees a maximum offset voltage drift of 2 µV/°C over −40°C to +125°C. This value is tested and binned per unit-not just typical-and directly impacts long-term calibration stability in unattended systems like environmental monitoring stations where the ADA4610-2ACPZ-R7 maintains accuracy without periodic recalibration.
