Product details
Overview
OP296GSZ-REEL from Analog Devices is a dual micropower rail-to-rail input/output operational amplifier optimized for battery-powered instrumentation and sensor conditioning. It delivers 450 kHz gain bandwidth, 0.3 V/µs slew rate, 300 µV max input offset voltage, 60 µA supply current per amplifier, and operates from 3 V to 12 V single supply - enabling precision signal amplification in portable power supply control and low-voltage monitoring systems.
For engineers reviewing the OP296GSZ-REEL datasheet, OP296GSZ-REEL pinout, OP296GSZ-REEL application, or OP296GSZ-REEL equivalent, key selection criteria include guaranteed rail-to-rail swing at 3 V, industrial temperature range (–40°C to +125°C), no phase reversal under overvoltage, capacitive load stability up to 200 pF, and G-grade offset performance with long-term drift of 1.5 µV/°C.
Technical Context
The OP296GSZ-REEL employs a composite PNP/NPN input stage enabling true rail-to-rail common-mode input range (0 V to VS) and output swing within 70 mV of rails at ±100 µA load. Its micropower architecture achieves 60 µA/amplifier quiescent current while maintaining 500 V/mV large-signal open-loop gain and 47° phase margin for unity-gain stability.
It features no output phase reversal when inputs exceed supply rails - a critical advantage over conventional single-supply op amps - and supports stable operation with capacitive loads ≤200 pF without external compensation. The device is specified across –40°C to +125°C and supports 3 V operation down to 0°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 450 kHz - enables stable closed-loop operation up to ~40 kHz at gain = 10 without excessive phase lag. |
| Supply Current per Amplifier | 60 µA - allows continuous operation for >1 year on a single CR2032 coin cell in low-duty-cycle sensor nodes. |
| Input Offset Voltage (max) | 300 µV - ensures ≤0.3% error in 100 mV full-scale sensor outputs without trimming. |
| Output Swing (IL = ±100 µA) | Within 70 mV of rails - supports full dynamic range utilization in 3 V ADC interfaces. |
| Common-Mode Input Range | 0 V to VS - permits direct interfacing with ground-referenced sensors and DACs without level-shifting. |
| Operating Temperature Range | –40°C to +125°C - qualified for automotive cabin, industrial motor control, and outdoor IoT deployments. |
| Voltage Noise Density | 26 nV/√Hz at 1 kHz - suitable for low-frequency (<10 kHz) precision amplification of thermocouples and RTDs. |
Pinout & Package
OP296GSZ-REEL is housed in an 8-lead narrow-body SOIC (SOIC_N) package per JEDEC MS-012-AA, with 1.27 mm lead pitch and 5.00 × 4.00 mm body dimensions. Thermal resistance θJA is 158°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT A | Amplifier A output | Drives loads up to ±4 mA; rail-to-rail swing supports 3 V logic-compatible output levels. |
| 2 - –IN A | Inverting input A | Differential node for feedback networks; accepts common-mode voltages from 0 V to VS. |
| 3 - +IN A | Non-inverting input A | High-impedance sensor interface point; input bias current ≤50 nA minimizes leakage errors. |
| 4 - V– | Negative supply / ground reference | Connects to system ground or negative rail; serves as return path for both amplifiers. |
| 5 - OUT B | Amplifier B output | Independent output channel; identical AC/DC specs to OUT A for dual-channel signal processing. |
| 6 - –IN B | Inverting input B | Second differential input; enables independent gain stages or instrumentation configurations. |
| 7 - +IN B | Non-inverting input B | Second high-Z input; supports dual-sensor readout or active filtering topologies. |
| 8 - V+ | Positive supply | Accepts 3 V to 12 V single supply; PSRR ≥85 dB rejects supply ripple in battery-powered systems. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower RRIO operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Higher supply current (550 µA/amplifier); wider GBW (6.4 MHz); higher offset (2 mV max); not specified below 0°C. | Better for higher-speed, AC-coupled sensor interfaces; unsuitable for multi-year battery life requirements. | Select TLV2462IDR only if bandwidth >1 MHz is required and power budget allows >9× higher quiescent current. |
| AD8602ARZ | Lower offset (65 µV max); lower noise (12 nV/√Hz); higher supply current (120 µA/amplifier); narrower supply range (2.7–6 V). | Preferred for ultra-low-offset precision applications at 5 V; cannot operate at 12 V or below 2.7 V. | Choose AD8602ARZ when offset and noise dominate design constraints and supply is fixed at 5 V. |
Compared with TLV2462IDR and AD8602ARZ, OP296GSZ-REEL uniquely balances ultra-low power (60 µA), wide supply range (3–12 V), and industrial temperature rating - making it the only option among the three qualified for 12 V automotive subsystems with multi-year battery runtime.

FAQ
What is the maximum capacitive load the OP296GSZ-REEL can drive without oscillation?
The OP296GSZ-REEL is unconditionally stable with capacitive loads up to 200 pF in unity-gain configuration, as confirmed in the datasheet's "Driving Capacitive Loads" section. This eliminates need for external isolation resistors when interfacing with typical ADC input capacitances (10–30 pF) or long PCB traces. For loads >200 pF, in-the-loop compensation (e.g., series resistor + feedback capacitor) is recommended per Figure 4 of the OP296GSZ-REEL datasheet.
Does the OP296GSZ-REEL support true rail-to-rail input at 3 V supply?
Yes - the OP296GSZ-REEL guarantees rail-to-rail input common-mode range from 0 V to VS at 3 V supply, validated across the full industrial temperature range (–40°C to +125°C). This allows direct connection to ground-referenced sensors and 3 V DAC outputs without level-shifting circuitry, as documented in the "Input Voltage Range" specification table (VCM = 0 V to 3.0 V at 0°C to 125°C).
What is the guaranteed input offset voltage specification for OP296GSZ-REEL over temperature?
The OP296GSZ-REEL (G-grade) has a maximum input offset voltage of 300 µV at 25°C and 650 µV over the full –40°C to +125°C range, per the "INPUT CHARACTERISTICS" table. Its offset voltage drift is tightly controlled at 1.5 µV/°C (average of –40°C to +25°C and +25°C to +125°C deltas), ensuring predictable error accumulation in precision DC-coupled circuits.
Can OP296GSZ-REEL be used in a single-supply 3 V LDO feedback loop?
Yes - the OP296GSZ-REEL is explicitly validated for this use case in the "A 3 V Low Dropout, Linear Voltage Regulator" application circuit (Figure 8). Its rail-to-rail output swing (within 70 mV of 3 V rail at ±100 µA) fully drives the base of a PNP pass transistor, and its 60 µA supply current minimizes regulator quiescent loss - enabling efficient, low-dropout regulation in space-constrained portable designs.
Is OP296GSZ-REEL susceptible to output phase reversal when inputs exceed supply rails?
No - the OP296GSZ-REEL uses a novel composite PNP/NPN input stage that eliminates output phase reversal, even when inputs are driven beyond V– or V+ by up to 0.6 V. This behavior is confirmed in Figure 2 ("Output Voltage Phase Reversal Behavior") and the "Output Phase Reversal" subsection, distinguishing it from conventional single-supply op amps that require external clamping diodes.
