Product details
Overview
AD8617WARMZ-REEL from Analog Devices is a dual-channel, micropower, rail-to-rail input/output operational amplifier qualified for automotive applications. It operates from 1.8 V to 5.5 V single supply, delivers 22 nV/√Hz voltage noise at 10 kHz, consumes ≤50 μA per amplifier over temperature, and features 2.2 mV max offset voltage - enabling precision signal conditioning in battery-constrained automotive sensor interfaces and shunt current monitoring.
For engineers reviewing the AD8617WARMZ-REEL datasheet, AD8617WARMZ-REEL pinout, AD8617WARMZ-REEL application, or AD8617WARMZ-REEL equivalent, key selection criteria include its AEC-Q100 qualification, 8-lead MSOP package with exposed pad, guaranteed performance across −40°C to +125°C, and compatibility with low-voltage CMOS ADC predriver and DAC level-shifter topologies.
Technical Context
The AD8617WARMZ-REEL implements a CMOS input stage with 1 pA max input bias current and rail-to-rail swing on both input and output, supporting direct interfacing to 1.8 V logic and wide-dynamic-range sensors. Its unity-gain stable architecture achieves 350 kHz gain-bandwidth product at 10 kΩ load and 70° phase margin with 20 pF capacitive load.
Designed for automotive-grade reliability, it incorporates no-phase-reversal circuitry, operates with ±0.9 V dual supply or 1.8–5.5 V single supply, and maintains 68 dB CMRR and 64 dB PSRR over full temperature range - critical for noise-sensitive engine control and body electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V single supply - supports direct integration into 2.0 V–5.0 V automotive microcontroller I/O domains. |
| Offset Voltage (max) | 2.2 mV - enables <1% error in 12-bit current-sense applications with 100 mΩ shunt at 1 A. |
| Input Bias Current (max) | 1 pA at 25°C - preserves accuracy in high-impedance pH, thermopile, or piezoelectric sensor front-ends. |
| Quiescent Current (max) | 50 μA per amplifier - allows dual-opamp operation for <100 μA total system standby current in always-on modules. |
| Voltage Noise Density | 22 nV/√Hz at 10 kHz - meets SNR requirements for 16-bit ADC predriver stages in automotive data acquisition. |
| Gain Bandwidth Product | 350 kHz at RL = 10 kΩ - sufficient for anti-aliasing filters and closed-loop gain ≥10 with <1% settling error in <25 μs. |

Pinout & Package
AD8617WARMZ-REEL uses an 8-lead MSOP (RM-8) package with exposed thermal pad connected to V–. Pin 4 and the exposed pad must be soldered to ground plane for thermal stability and EMI suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives low-impedance loads up to 10 mA while maintaining rail-to-rail swing. |
| 2 | −IN A | Inverting input of Amplifier A - high-impedance node (1 pA bias) for precision feedback networks. |
| 3 | +IN A | Non-inverting input of Amplifier A - accepts common-mode signals from 0 V to VSY. |
| 4 | V– | Negative supply / ground reference - must be connected to PCB ground plane and exposed pad. |
| 5 | +IN B | Non-inverting input of Amplifier B - electrically isolated from Amplifier A; supports dual independent channels. |
| 6 | −IN B | Inverting input of Amplifier B - matched to Pin 2 for consistent common-mode rejection. |
| 7 | OUT B | Amplifier B output - identical AC/DC specs to OUT A; enables dual-path signal conditioning. |
| 8 | V+ | Positive supply - accepts 1.8–5.5 V; PSRR of 64 dB ensures immunity to power rail ripple. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full-scale signal buffering in 1.8 V systems without level-shifting components. |
| AEC-Q100 qualified (Grade 1) | Guarantees reliability for automotive powertrain, chassis, and body control modules. |
| No phase reversal | Prevents catastrophic output latch-up when input exceeds supply rails - critical for fault-tolerant designs. |
| Low 1/f noise corner at 100 Hz | Ensures stable DC accuracy in slow-response applications like cabin temperature sensing. |
| Unity-gain stable | Eliminates need for external compensation in buffer, gain-of-1, or follower configurations. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV912IDT | Higher 5.5 MHz GBW but 600 μA/quiescent current; not AEC-Q100 qualified. | Suitable for non-automotive industrial sensors requiring faster response; unsuitable for battery-backed modules. | Select only if speed >350 kHz is required and automotive qualification is unnecessary. |
| MCP6022-E/SN | Lower 175 μA quiescent current but 3.5 mV offset and no AEC-Q100 rating; 2.7–5.5 V supply range. | Fits cost-sensitive consumer-grade automotive accessories; lacks extended temperature validation. | Acceptable for cabin-only modules with ambient temperature limits ≤+85°C and relaxed offset tolerance. |
Compared with TSV912IDT and MCP6022-E/SN, AD8617WARMZ-REEL uniquely combines AEC-Q100 Grade 1 qualification, sub-50 μA quiescent current, and 2.2 mV offset - making it the only option for safety-critical, low-power, high-accuracy dual-opamp functions in modern vehicle ECUs.

FAQ
What is the operating temperature range for AD8617WARMZ-REEL?
AD8617WARMZ-REEL is specified for −40°C to +125°C operation and qualified to AEC-Q100 Grade 1 standards. All electrical parameters - including offset voltage, CMRR, and supply current - are guaranteed across this full range, making AD8617WARMZ-REEL suitable for under-hood and transmission-control applications where ambient temperatures exceed 105°C.
Does AD8617WARMZ-REEL require external compensation for unity-gain stability?
No, AD8617WARMZ-REEL is internally compensated and unity-gain stable. It achieves 70° phase margin with 20 pF capacitive load at 10 kΩ gain-setting resistance, eliminating the need for external compensation components in buffer, follower, or gain-of-1 configurations - a key advantage in space-constrained automotive PCB layouts.
How is the exposed thermal pad on AD8617WARMZ-REEL connected?
The exposed pad on AD8617WARMZ-REEL must be soldered to Pin 4 (V–) and the PCB ground plane. Per the datasheet note, "PIN 4 AND THE EXPOSED PAD MUST BE CONNECTED TO V–." This connection provides thermal dissipation and reduces thermal impedance (θJC = 45°C/W), ensuring junction temperature remains within safe limits during continuous 10 mA output operation.
Is AD8617WARMZ-REEL pin-compatible with non-automotive AD8617 variants?
Yes, AD8617WARMZ-REEL shares identical pinout, footprint, and electrical interface with AD8617ARMZ-REEL and AD8617ARZ-REEL. The "W" suffix denotes AEC-Q100 qualification and tighter test screening - no layout changes are needed when upgrading from commercial to automotive grade in existing MSOP-based designs.
What is the maximum capacitive load AD8617WARMZ-REEL can drive without instability?
AD8617WARMZ-REEL maintains stable operation with up to 20 pF capacitive load at unity gain, as verified by 70° phase margin in the datasheet's Figure 14. For loads exceeding 20 pF, a series isolation resistor (≥100 Ω) between output and capacitance is recommended to preserve stability - a common practice in ADC driver and filter applications.
