Product details

Overview

AD8604ARZ-REEL7 from Analog Devices is a quad-channel, rail-to-rail input/output precision CMOS operational amplifier optimized for single-supply operation from 2.7 V to 5.5 V. It delivers 8 MHz gain bandwidth, 5 V/µs slew rate, 500 µV max offset voltage (A grade), 750 µA per amplifier supply current, and operates across −40°C to +125°C - enabling high-accuracy signal conditioning in battery-powered instrumentation and sensor interfaces.

For engineers reviewing the AD8604ARZ-REEL7 datasheet, AD8604ARZ-REEL7 pinout, AD8604ARZ-REEL7 application, or AD8604ARZ-REEL7 equivalent, key selection criteria include rail-to-rail I/O swing at low supply voltage, ultra-low input bias current (0.2 pA typ), wide common-mode range (0 V to V_S), no phase reversal behavior, and AEC-Q100 qualification for automotive-grade reliability.

Technical Context

The AD8604ARZ-REEL7 implements a dual-input-stage architecture with parallel NMOS and PMOS differential pairs to achieve true rail-to-rail input common-mode range (0 V to V_S). Its DigiTrim® post-package trimming eliminates mechanical stress-induced offset drift, delivering stable 500 µV max V_OS over temperature without laser trimming.

Output stage uses complementary NMOS/PMOS common-source configuration for rail-to-rail swing; output reaches within 15 mV of V_S and 20 mV of GND at 1 mA load. Open-loop gain is 80 dB (typ) into 2 kΩ, with phase margin of 50°–55° ensuring unity-gain stability across supply voltages and temperatures.

Key Specifications

Parameter	Value and Actual Design Meaning
Gain Bandwidth Product	8.2–8.4 MHz - supports stable closed-loop operation up to ~1 MHz at G = 10 without excessive phase lag.
Slew Rate	5.2–6 V/µs - enables accurate reproduction of >1 V_PP signals at ~1 MHz without slew-induced distortion.
Input Offset Voltage (max)	600 µV (A grade, 25°C) - ensures ≤0.12% error in 0.5 V full-scale shunt current sensing at room temperature.
Supply Current per Amplifier	750 µA (typ, 5 V) - allows four amplifiers to operate on <3 mA total, critical for multi-channel portable instruments.
Input Bias Current	0.2 pA (typ) - permits use with >100 MΩ source impedances (e.g., photodiode, pH electrode) without significant offset error.
Rail-to-Rail Output Swing	Within 15 mV of V_S, 20 mV of GND @ 1 mA - fully buffers 3.3 V ADCs/DACs and ASIC I/O without level-shifting circuitry.
Operating Temperature Range	−40°C to +125°C - qualified for under-hood automotive, industrial control, and extended-environment sensor nodes.

Pinout & Package

AD8604ARZ-REEL7 is packaged in a 14-lead TSSOP (RU suffix) with exposed pad for thermal enhancement. Pin numbering follows standard JEDEC outline MS-012AA.

Pin/Terminal	Circuit Role	Design Meaning
1	−IN A	Inverting input of Amplifier A - high-impedance node (0.2 pA bias) for precision feedback networks.
2	+IN A	Non-inverting input of Amplifier A - accepts common-mode signals from 0 V to V_S without clipping.
3	V+	Positive supply rail - accepts 2.7 V to 5.5 V; decoupling capacitor required at pin for stability.
4	OUT B	Output of Amplifier B - drives loads up to ±50 mA; rail-to-rail swing enables direct interface to 3.3 V logic.
5	−IN B	Inverting input of Amplifier B - electrically identical to Pin 1; supports independent channel configuration.
6	+IN B	Non-inverting input of Amplifier B - matched offset and bias performance to Pins 1–2 for multi-channel coherence.
7	OUT A	Output of Amplifier A - same drive capability and voltage swing as Pin 4; shares V+ and V− rails with other channels.
8	V−	Negative supply rail (GND) - return path for all four amplifiers; low-impedance connection essential for noise immunity.
9	OUT D	Output of Amplifier D - fully independent output stage; supports simultaneous multi-signal conditioning.
10	−IN C	Inverting input of Amplifier C - part of fourth channel; maintains sub-pA bias across all inputs.
11	+IN C	Non-inverting input of Amplifier C - identical electrical specs to Pins 2, 6, 14; enables matched quad design.
12	V−	Second GND connection - reduces ground bounce in high-speed multi-channel layouts; must be tied to main GND plane.
13	+IN D	Non-inverting input of Amplifier D - completes quad set; all +IN pins share same CMRR (74–89 dB) and input voltage range.
14	−IN D	Inverting input of Amplifier D - final high-impedance node; supports independent gain-setting resistors per channel.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
OPA4340UA	Wider supply range (2.7–36 V), higher V_OS (1.5 mV max), 10× higher supply current (7.5 mA/ch).	Preferred in high-voltage industrial sensors; unsuitable for ultra-low-power portable designs.	Select AD8604ARZ-REEL7 when supply is ≤5.5 V and quiescent current <3 mA is mandatory.
TSV914IQ4T	Lower cost, lower GBW (4 MHz), higher V_OS (1.5 mV max), not AEC-Q100 qualified.	Targeted at consumer electronics; lacks automotive qualification and precision for metrology-grade sensing.	Choose AD8604ARZ-REEL7 for automotive, medical, or industrial applications requiring guaranteed 600 µV V_OS and −40°C to +125°C operation.

Compared with OPA4340UA and TSV914IQ4T, AD8604ARZ-REEL7 uniquely balances ultra-low power (750 µA/ch), precision (600 µV V_OS), rail-to-rail operation, and automotive qualification - making it optimal for space-constrained, battery-sensitive, and safety-critical signal chains where alternative parts compromise on at least two of these attributes.

FAQ

What is the maximum operating supply voltage for AD8604ARZ-REEL7?

The absolute maximum supply voltage for AD8604ARZ-REEL7 is 6 V, but the recommended operating range is 2.7 V to 5.5 V. Operation above 5.5 V risks permanent damage and violates the device's specified electrical characteristics - including offset voltage, bandwidth, and output swing - which are only guaranteed within the 2.7–5.5 V window per the Rev. I datasheet.

Does AD8604ARZ-REEL7 support rail-to-rail input with a 3.3 V supply?

Yes, AD8604ARZ-REEL7 supports true rail-to-rail input with a 3.3 V supply: its input common-mode voltage range extends from 0 V to 3.3 V, verified across temperature and process corners. This allows direct interfacing with 3.3 V microcontroller GPIOs, DAC outputs, or sensor bridges without external level-shifting circuitry.

Is AD8604ARZ-REEL7 qualified for automotive applications?

Yes, AD8604ARZ-REEL7 is AEC-Q100 qualified (Grade 1: −40°C to +125°C ambient), with full characterization for automotive use cases including engine control, body electronics, and ADAS sensor signal conditioning. The datasheet explicitly lists "Qualified for automotive applications" in the FEATURES section and references automotive ordering options in the Ordering Guide.

What is the typical input bias current of AD8604ARZ-REEL7 at 25°C?

The typical input bias current of AD8604ARZ-REEL7 is 0.2 pA at 25°C, with a maximum of 60 pA over the full −40°C to +125°C range. This ultra-low value enables high-impedance applications such as photodiode transimpedance amplifiers, pH electrodes, and piezoelectric sensor interfaces without measurable gain error or drift.

Can AD8604ARZ-REEL7 drive a 10 kΩ load while maintaining rail-to-rail output swing?

Yes, AD8604ARZ-REEL7 maintains rail-to-rail output swing into 10 kΩ loads: at 5 V supply and 25°C, it delivers VOH ≥ 4.925 V and VOL ≤ 30 mV (i.e., within 75 mV of rails) with 1 mA load - well within specification for 10 kΩ (0.5 mA). Performance is confirmed in Figure 17 and Table 2 of the Rev. I datasheet.
