Product details
Overview
OP292GSZ from Analog Devices is a dual, single-supply operational amplifier optimized for 5 V systems, featuring rail-to-ground output swing, 4 MHz gain bandwidth, 3 V/µs slew rate, and input common-mode range extending to ground - enabling precision signal conditioning in battery-powered instrumentation and mobile phone analog front-ends.
For engineers reviewing the OP292GSZ datasheet, OP292GSZ pinout, OP292GSZ application, or OP292GSZ equivalent, this page delivers verified electrical specifications, thermal performance data, real-world single-supply circuit implementations (e.g., DAC output buffering, notch filtering), and validated alternative options for industrial temperature-range (-40°C to +125°C) designs.
Technical Context
The OP292GSZ employs a PNP input stage enabling true ground-referenced input operation and a BiCMOS output stage supporting rail-to-ground output swing while sinking current - critical for single-supply sensor interfaces and DAC buffers. It is unity-gain stable with 75° phase margin and no phase inversion under normal operating conditions.
Specified for both single-supply (4.5 V to 33 V) and dual-supply (±2.25 V to ±15 V) operation, the device maintains 4 MHz GBP and >100 dB channel separation at 1 kHz across the full −40°C to +125°C extended industrial temperature range, with guaranteed open-loop gain ≥25 V/mV (RL = 10 kΩ) at 125°C.
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 logic systems without level-shifting. |
| Gain Bandwidth Product | 4 MHz - enables stable closed-loop amplification up to ~300 kHz at unity gain for audio and sensor signal paths. |
| Slew Rate | 3 V/µs (typ, RL = 10 kΩ) - sufficient for settling 12-bit DAC outputs within <1 µs to 0.1% accuracy. |
| Input Offset Voltage | 0.8 mV max (25°C), 2.5 mV max (−40°C to +125°C) - ensures ≤12-bit linearity in precision transducer interfaces. |
| Output Swing (Low) | ≤20 mV above ground (RL = 100 kΩ) - allows true 0 V output reference in single-supply ADC driver stages. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive sensors, industrial motor controls, and telecom power supplies. |
| Input Bias Current | 700 nA max (25°C), 5 µA max (125°C) - compatible with high-impedance thermistor and photodiode front-ends. |
Pinout & Package
OP292GSZ is housed in an 8-lead narrow-body SOIC (S-suffix) package with standard dual op amp pinout and 158°C/W junction-to-ambient thermal resistance.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Inverting amplifier output A - drives loads down to 2 kΩ while maintaining rail-to-ground swing. |
| 2 | –INA | Inverting input A - accepts signals from 0 V to 4.0 V common-mode range at 5 V supply. |
| 3 | +INA | Non-inverting input A - enables ground-referenced differential sensing with matched input impedance. |
| 4 | –V | Negative supply / ground pin - must be connected to system ground in single-supply configurations. |
| 5 | +INB | Non-inverting input B - electrically isolated from Channel A; supports independent signal paths. |
| 6 | –INB | Inverting input B - shares same input voltage range and bias current specs as Pin 2. |
| 7 | OUTB | Output B - identical AC/DC performance to OUTA; enables dual-channel signal processing on one die. |
| 8 | +V | Positive supply pin - accepts 4.5 V to 33 V; requires 0.1 µF ceramic bypass capacitor per supply pin. |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply operation from 4.5 V | Eliminates need for split supplies in portable 5 V systems - reduces BOM count and PCB area. |
| Input common-mode range includes ground | Enables direct interfacing with 0 V-referenced sensors (e.g., thermocouples, bridge transducers) without level-shifting. |
| Rail-to-ground output swing | Supports full-scale ADC input ranges (e.g., 0–4.096 V) without external level translation or negative bias. |
| No phase inversion | Prevents catastrophic output reversal during overdrive - critical for closed-loop servo and power control circuits. |
| High channel separation (100 dB @ 1 kHz) | Minimizes crosstalk between dual channels in instrumentation amplifiers and multi-channel data acquisition. |
Applications
| Mobile Phone Audio Interface | Disk Drive Servo Control |

| Battery-Operated Instrumentation | Power Supply Monitor & Control |
|

IC Role / Device Role: Precision dual amplifier - first stage provides low-noise gain; second stage implements offset correction and output buffering. Use Value: 15 nV/√Hz voltage noise density and 0.8 mV max offset enable ±0.3°C accuracy over 0–70°C without calibration. |
Use Scenario: Monitoring DC bus voltage and current in industrial SMPS, triggering overvoltage/undervoltage protection thresholds. IC Role / Device Role: Dual comparator/amplifier - one channel compares sensed voltage against reference; other implements hysteresis or latch function. Use Value: Input common-mode to ground allows direct sensing of 0 V-referenced shunt resistors; 4 MHz bandwidth supports fast fault detection. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358DR | Lower GBP (1 MHz), higher offset (3 mV max), no guaranteed rail-to-ground output at 125°C. | Acceptable for cost-sensitive consumer-grade 25°C-only applications; not suitable for extended temperature or precision 0 V output. | Select LM358DR only if operating strictly at 25°C with >10 mV offset tolerance and no rail-to-ground requirement. |
| TLV2462IDR | Lower supply current (550 µA/ch), rail-to-rail I/O, but lower slew rate (0.6 V/µs) and narrower temp range (−40°C to +125°C same). | Better for ultra-low-power battery life; insufficient for fast DAC buffering or servo control due to limited slew rate. | Choose TLV2462IDR when sub-1 mA total supply current is mandatory and signal bandwidth <100 kHz. |
Compared with LM358DR and TLV2462IDR, OP292GSZ uniquely balances 4 MHz bandwidth, 3 V/µs slew rate, rail-to-ground output, and full −40°C to +125°C qualification - making it the only option among the three for precision, high-speed, wide-temperature single-supply instrumentation.

FAQ
What is the maximum operating temperature for OP292GSZ?
The OP292GSZ is fully specified and guaranteed over the extended industrial temperature range of −40°C to +125°C. Electrical parameters including input offset voltage (2.5 mV max), open-loop gain (5 V/mV min), and output swing (3.7 V min high, 12 mV max low) are tested and warranted across this full range - critical for under-hood automotive or high-ambient industrial deployments.
Does OP292GSZ support true rail-to-ground output swing?
Yes, OP292GSZ guarantees output swing to within 20 mV of ground (low-side) with 100 kΩ load at 25°C, and to within 550 mV at 125°C - confirmed in Table 1 of the Rev. D datasheet. This rail-to-ground capability is enabled by its BiCMOS output stage and is essential for interfacing with 0 V–referenced ADCs and comparators in single-supply systems.
Can OP292GSZ be used with a 3.3 V supply?
No - the absolute minimum supply voltage for OP292GSZ is 4.5 V, as stated in the Features section and Absolute Maximum Ratings table. Operation below 4.5 V risks undefined behavior, reduced output swing, and failure to meet specified slew rate or bandwidth. For 3.3 V systems, consider alternatives like AD8602 or TLV2462 with verified 2.7 V–5.5 V operation.
Is OP292GSZ pin-compatible with OP292GRUZ?
No - OP292GSZ uses an 8-lead narrow-body SOIC package (SOIC_N), while OP292GRUZ uses an 8-lead MSOP package. Though both contain identical die and electrical specs, their footprints, thermal resistance (θJA = 158°C/W vs. 200°C/W), and soldering profiles differ. PCB layout and reflow must be redesigned for package interchange.
What is the typical supply current per amplifier for OP292GSZ?
The typical supply current per amplifier for OP292GSZ is 1.2 mA at 5 V and 25°C (Table 1), rising to 1.4 mA at ±15 V (Table 2). At 125°C, supply current increases to ~1.3 mA (Figure 15). This low quiescent current enables use in always-on battery monitoring circuits while maintaining 4 MHz bandwidth and 3 V/µs slew rate.
