Product details

Overview

ADA4622-4ARZ-RL from Analog Devices is a quad-channel, rail-to-rail output (RRO), precision JFET-input operational amplifier optimized for high-impedance sensor interfaces and ADC driving. It delivers 8 MHz gain bandwidth, ±10 pA max input bias current at 25°C, ±0.35 mV max offset voltage (B grade), −40°C to +125°C operation, and 5 V to 30 V single/dual supply support - enabling low-noise signal conditioning in photodiode preamps and precision filters.

For engineers reviewing the ADA4622-4ARZ-RL datasheet, ADA4622-4ARZ-RL pinout, ADA4622-4ARZ-RL application, or ADA4622-4ARZ-RL equivalent, key selection criteria include its 14-pin SOIC_N package, quad-channel matching specs (±1 mV max offset match), EMI rejection (90 dB at 1 GHz/2.4 GHz), and verified performance at ±5 V, ±15 V, and 5 V supplies - critical for industrial sensor front-ends and SAR ADC driver designs.

Technical Context

The ADA4622-4ARZ-RL implements a JFET-input stage with input voltage range extending to V− and rail-to-rail output swing, supporting true single-supply operation down to 5 V. Its architecture integrates on-chip EMI filtering to suppress switching noise at 1 GHz and 2.4 GHz without external components.

It features matched quad channels with guaranteed offset voltage matching of ±1 mV over temperature and crosstalk of −106 dB at 1 kHz, enabling multi-channel instrumentation where channel-to-channel interference must be minimized - such as in 4-channel data acquisition systems or differential signal chains with shared reference paths.

Key Specifications

Pinout & Package

ADA4622-4ARZ-RL is housed in a 14-lead SOIC_N package (body width 3.9 mm, pitch 1.27 mm), with exposed pad not present. Pin 1 is OUT A; pins 13 and 16 are NIC (Not Internally Connected). The device requires no external shutdown control - unlike the LFCSP variant, this SOIC version lacks a DISABLE pin.

2	−IN A	Inverting input for Channel A - forms feedback node in standard op-amp configurations.
3	+IN A	Noninverting input for Channel A - accepts common-mode voltages down to V−.
4	V+	Positive supply rail - connects to main system VCC (5–30 V); powers all four amplifiers.
5	+IN B	Noninverting input for Channel B - electrically isolated but thermally coupled to other channels.
6	−IN B	Inverting input for Channel B - matches A-channel input characteristics per datasheet matching specs.
7	OUT B	Amplifier B output - identical AC/DC specs to OUT A; crosstalk < −106 dB at 1 kHz.
8	OUT C	Amplifier C output - enables simultaneous 4-channel signal processing without external multiplexing.
9	−IN C	Inverting input for Channel C - shares same input capacitance (0.4 pF diff, 3.6 pF cm) as other channels.
10	+IN C	Noninverting input for Channel C - supports common-mode range from V− to (V+ − 1 V).
11	V−	Negative supply rail - connects to ground (single supply) or negative rail (dual supply); referenced by all inputs/outputs.
12	+IN D	Noninverting input for Channel D - enables independent 4th channel gain/offset adjustment.
13	−IN D	Inverting input for Channel D - matched offset drift (±2 µV/°C B grade) ensures thermal tracking across all channels.
14	OUT D	Amplifier D output - completes quad functionality; total quiescent current is 2.8 mA typical at ±15 V.

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar precision op amp applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
OP4177ARZ	Bipolar input (vs. JFET); higher IB (±2 nA); lower GBP (1.3 MHz); no EMI filtering.	Better DC precision (±60 µV offset) but unsuitable for >100 kΩ source impedances or RF-noisy environments.	Select when ultra-low offset drift (0.3 µV/°C) outweighs speed and input impedance requirements.
ADA4625-4ARUZ	Higher GBP (18 MHz); lower noise (7.9 nV/√Hz); same JFET input; adds shutdown pin.	Superior dynamic performance for wideband active filters or high-speed sensor interfaces, but higher supply current (1.2 mA/ch).	Select when bandwidth >10 MHz or voltage noise <8 nV/√Hz is required - at cost of increased power and layout complexity.

Compared with OP4177ARZ and ADA4625-4ARUZ, ADA4622-4ARZ-RL uniquely balances 8 MHz bandwidth, pA-level input bias, integrated EMI rejection, and quad-channel matching in a standard SOIC package - making it optimal for cost-sensitive, noise-resilient, multi-sensor industrial signal chains where moderate speed suffices.

FAQ

What supply voltage ranges does the ADA4622-4ARZ-RL support?

The ADA4622-4ARZ-RL operates from a single 5 V supply up to 30 V, or dual supplies from ±5 V to ±15 V. At 5 V single supply, it maintains rail-to-rail output swing and specified offset voltage (±0.35 mV B grade), making ADA4622-4ARZ-RL suitable for modern low-voltage industrial I/O modules without level-shifting circuitry.

Does the ADA4622-4ARZ-RL have a shutdown pin?

No, the ADA4622-4ARZ-RL in the 14-lead SOIC_N package does not include a shutdown pin. Shutdown functionality is only available on the LFCSP variants (e.g., ADA4622-4ACPZ-R7). The SOIC version draws 2.8 mA typical quiescent current at ±15 V and cannot be externally disabled - ADA4622-4ARZ-RL must be powered down at the supply rail for zero-current operation.

What is the maximum input common-mode voltage for ADA4622-4ARZ-RL?

At ±15 V supply, the input common-mode voltage range for ADA4622-4ARZ-RL extends from (V−) −0.2 V to (V+) −1 V - i.e., −15.2 V to +14 V. This allows direct interfacing with signals referenced to ground in single-supply systems and supports true rail-to-rail input capability near the negative rail, critical for high-side current sensing and bipolar signal conditioning.

How does the ADA4622-4ARZ-RL handle electromagnetic interference?

The ADA4622-4ARZ-RL incorporates on-chip EMI filtering that provides 90 dB rejection at both 1000 MHz and 2400 MHz - confirmed in the datasheet's EMIRR test conditions. This built-in immunity eliminates the need for external RC filters in applications near switching power supplies or wireless transceivers, ensuring stable operation in electrically noisy factory floors without added board area or component count for ADA4622-4ARZ-RL.

Is the ADA4622-4ARZ-RL pin-compatible with older AD824 op-amps?

Yes, the ADA4622-4ARZ-RL uses the same 14-lead SOIC_N pinout as the AD824, including identical assignments for all four amplifier channels, supply pins, and inputs. This allows drop-in replacement in existing AD824-based designs - ADA4622-4ARZ-RL delivers higher bandwidth (8 MHz vs. 1 MHz), lower input bias current (±10 pA vs. ±250 pA), and integrated EMI filtering without PCB layout changes.
