Product details
Overview
OP292GSZ-REEL from Analog Devices is a dual, single-supply operational amplifier optimized for 5 V systems, featuring rail-to-ground output swing, input common-mode range extending to ground, 4 MHz gain bandwidth, 3 V/µs slew rate, and 0.8 mV max input offset voltage at +25°C. It serves as a precision signal conditioning amplifier in battery-powered instrumentation and telecom interface circuits.
For engineers reviewing the OP292GSZ-REEL datasheet, OP292GSZ-REEL pinout, OP292GSZ-REEL application, or OP292GSZ-REEL equivalent, key selection criteria include guaranteed ground-swing output under 2 kΩ load, PNP-input stage enabling true single-supply operation down to 4.5 V, −40°C to +125°C extended industrial temperature rating, and BiCMOS output stage supporting sink current to ground.
Technical Context
The OP292GSZ-REEL employs a PNP input stage that enables input common-mode voltage to include ground - critical for single-supply sensor interfacing - and a BiCMOS output stage allowing output to swing to ground while sinking current. Its unity-gain stable architecture delivers 4 MHz bandwidth with 75° phase margin and 100 dB channel separation at 1 kHz.
Specified for both single-supply (4.5 V to 33 V) and dual-supply (±2.25 V to ±15 V) operation, it maintains high open-loop gain (>25 V/mV at 2 kΩ load), low input bias current (700 nA typ), and no phase inversion - even when inputs exceed the negative rail by 5 V or the positive rail by 0.6 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 33 V single supply; supports direct integration into 5 V microcontroller systems without level-shifting. |
| Gain Bandwidth Product | 4 MHz - enables stable closed-loop amplification up to ~300 kHz at gain = 10, suitable for audio and sensor signal conditioning. |
| Slew Rate | 3 V/µs (typ at 5 V) - supports clean 100 kHz sine wave output at 3 Vpp without distortion. |
| Input Offset Voltage | 0.8 mV max (25°C), 2.5 mV max (−40°C to +125°C) - ensures <±1 LSB error in 12-bit DAC buffering applications. |
| Output Swing (Low) | 20 mV above ground (RL = 100 kΩ), 550 mV above ground (RL = 2 kΩ) - enables true ground-referenced output in low-voltage systems. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive sensors, industrial motor controls, and outdoor metering equipment. |
| Input Common-Mode Range | 0 V to 4.0 V (VS = 5 V) - accepts ground-referenced transducer outputs without external biasing resistors. |
Pinout & Package
OP292GSZ-REEL is housed in an 8-lead narrow-body SOIC (SO-8, S-suffix), RoHS-compliant, tape-and-reel packaging format (REEL). Thermal resistance θJA = 158°C/W, θJC = 43°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUTA | Amplifier A output | Delivers rail-to-ground analog output; capable of sourcing/sinking ≥5 mA. |
| 2 - –INA | Inverting input A | Accepts differential or single-ended signals; PNP input allows common-mode down to ground. |
| 3 - +INA | Non-inverting input A | High-impedance node (700 nA bias current); used for reference or sensor connection. |
| 4 - –V | Negative supply / ground | Must be connected to system ground in single-supply mode; critical for proper input/output range. |
| 5 - +INB | Non-inverting input B | Independent second amplifier input; shares same process and specs as Channel A. |
| 6 - –INB | Inverting input B | Enables dual-channel configurations such as instrumentation amps or dual feedback paths. |
| 7 - OUTB | Amplifier B output | Electrically isolated from OUTA; supports independent loading and routing. |
| 8 - +V | Positive supply | Accepts 4.5–33 V; bypass with 0.1 µF ceramic capacitor recommended for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-ground output swing | Drives loads to within 20 mV of ground (100 kΩ), enabling true single-supply signal chain design without negative rails. |
| Input common-mode includes ground | PNP input stage permits direct connection of ground-referenced sensors (e.g., thermistors, bridge outputs) without bias networks. |
| No phase reversal | Immune to output polarity inversion when inputs exceed negative rail by 5 V or positive rail by 0.6 V - improves system reliability in transient conditions. |
| High channel separation | 100 dB at 1 kHz - prevents crosstalk between dual channels in mixed-signal applications like dual DAC buffers or stereo audio preamps. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358IDR | Lower slew rate (1 V/µs), lower GBP (1 MHz), rail-to-rail output (not input), 0.8 mV offset (max). | Not suitable for >100 kHz signal conditioning; lacks ground-swing input capability - requires external bias for ground-referenced sensors. | Select LMV358IDR only for cost-sensitive, low-bandwidth applications where input common-mode range >0 V is acceptable. |
| TLV2462CDR | Higher quiescent current (550 µA/amp vs 1.2 mA), rail-to-rail I/O, 2.5 V to 6 V supply range, 2.5 mV offset (max). | Cannot operate at 4.5–33 V; limited to low-voltage systems; higher noise density (28 nV/√Hz vs 15 nV/√Hz). | Choose TLV2462CDR only for ultra-low-voltage (≤3.3 V) portable designs where rail-to-rail input is mandatory and bandwidth ≤2 MHz suffices. |
Compared with LMV358IDR and TLV2462CDR, OP292GSZ-REEL uniquely combines ground-swing input *and* output, 4 MHz bandwidth, and extended 4.5–33 V supply range - making it the only option among the three qualified for 5 V industrial sensor nodes requiring full ground-referenced dynamic range and robust transient immunity.

FAQ
What supply voltage range does the OP292GSZ-REEL support?
The OP292GSZ-REEL operates from 4.5 V to 33 V on a single supply, or ±2.25 V to ±15 V on dual supplies. At 5 V single supply, it delivers full specified performance including ground-swing output and input common-mode down to 0 V. This makes OP292GSZ-REEL ideal for direct integration into 5 V microcontroller-based systems without voltage translation.
Does the OP292GSZ-REEL have rail-to-rail input and output capability?
The OP292GSZ-REEL features rail-to-ground output swing (down to 20 mV above ground) and input common-mode range that includes ground - but not full rail-to-rail input. Its PNP input stage enables operation with inputs at 0 V, critical for ground-referenced sensors. However, maximum input voltage is limited to V+ − 1 V, so it does not accept signals at the positive rail. OP292GSZ-REEL is optimized for true single-supply use, not universal rail-to-rail operation.
Can the OP292GSZ-REEL drive a 2 kΩ load while maintaining ground-swing output?
Yes - the OP292GSZ-REEL guarantees output swing to within 550 mV of ground when driving a 2 kΩ load to GND (−40°C to +125°C). At room temperature and 100 kΩ load, it swings to within 20 mV of ground. This capability is enabled by its BiCMOS output stage, which actively sinks current to ground. For applications requiring tighter ground margin under heavy load, consider adding a small series resistor or reducing load impedance per design validation.
Is the OP292GSZ-REEL susceptible to phase reversal?
No - the OP292GSZ-REEL is immune to phase reversal when inputs go below ground (up to 5 V negative) or slightly above V+ (up to 0.6 V). Phase reversal only occurs if the input exceeds V+ by more than 0.9 V, a condition easily avoided in properly biased circuits. Unlike many legacy op amps, OP292GSZ-REEL includes internal protection against this failure mode, enhancing reliability in transient-prone environments such as telecom line interfaces.
What is the maximum operating temperature specification for the OP292GSZ-REEL?
The OP292GSZ-REEL is fully specified over the extended industrial temperature range of −40°C to +125°C. All key parameters - including input offset voltage (2.5 mV max), open-loop gain (5 V/mV min), and output swing - are guaranteed across this range. This qualification makes OP292GSZ-REEL suitable for under-hood automotive modules, industrial motor drives, and outdoor utility metering where ambient temperatures exceed standard commercial limits.
