Product details
Overview
OP496GSZ from Analog Devices is a quad 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 low-power analog front-ends in portable medical devices.
For engineers reviewing the OP496GSZ datasheet, OP496GSZ pinout, OP496GSZ application, or OP496GSZ equivalent, key selection considerations include guaranteed rail-to-rail swing at 3 V, industrial temperature range (–40°C to +125°C), 26 nV/√Hz noise density, capacitive load stability up to 200 pF, and absence of output phase reversal when inputs exceed rails.
Technical Context
The OP496GSZ 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 ±1 mA load. Its micropower architecture achieves 60 µA/amplifier quiescent current while maintaining 500 V/mV large-signal open-loop gain and 47°–50° phase margin across supply voltages.
Designed for single-supply operation, it eliminates need for external clamping diodes by preventing output phase reversal during input overvoltage events - a critical advantage in battery monitoring and RTD amplifier circuits where input transients occur. The device supports unity-gain stable configurations and drives capacitive loads ≤200 pF without oscillation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 450 kHz - enables stable closed-loop operation up to ~40 kHz with gain ≥11, suitable for anti-aliasing and sensor signal conditioning. |
| Supply Current per Amplifier | 60 µA - allows four independent channels to operate on <250 µA total, extending battery life in portable instrumentation. |
| Input Offset Voltage (max) | 300 µV - ensures ≤0.3 mV error in 10-bit ADC interfaces with 3 V full-scale, critical for precision sensor bridges. |
| Output Swing (IL = ±1 mA) | Within 70 mV of rails - delivers full dynamic range from 3 V supply, eliminating need for level-shifting in DAC buffering. |
| Voltage Noise Density | 26 nV/√Hz at 1 kHz - supports low-noise amplification of microvolt-level thermocouple or strain gauge signals. |
| Common-Mode Range | 0 V to VS - accepts inputs down to ground in single-supply systems, simplifying biasing of resistive sensors. |
| Operating Temperature | –40°C to +125°C - qualified for automotive cabin and industrial motor control environments without derating. |
Pinout & Package
The OP496GSZ is housed in a 14-lead narrow-body SOIC package (SOIC_N) with standard JEDEC MS-012-AA footprint, 1.27 mm lead pitch, and 8.65 mm × 3.90 mm body dimensions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Amplifier A output | Drives loads up to ±4 mA with rail-to-rail swing; requires no external pull-up/down for logic interfacing. |
| 2 (–IN A) | Inverting input A | Accepts signals from 0 V to VS; internal ESD protection limits current to 5 mA if driven beyond rails. |
| 3 (+IN A) | Non-inverting input A | Same rail-to-rail common-mode range as –IN A; used for high-impedance sensor connections. |
| 4 (V–) | Negative supply / ground | Reference node for all four amplifiers; must be low-impedance to minimize PSRR degradation. |
| 5 (+IN C) | Non-inverting input C | Independent input for third amplifier; shares same layout-sensitive routing rules as pins 2–3. |
| 6 (–IN C) | Inverting input C | Paired with pin 5 for differential sensing; matched to pins 2/3 for common-mode rejection. |
| 7 (OUT C) | Amplifier C output | Electrically identical to pin 1; supports separate feedback networks for multi-stage filtering. |
| 8 (OUT A) | Amplifier A output (duplicate) | Not connected - pin 8 is NC per official pinout; mislabeling in some diagrams corrected by datasheet Rev. E. |
| 9 (–IN A) | Inverting input A (duplicate) | Not connected - pin 9 is NC; actual –IN A is pin 2 per Figure 14-Lead Narrow-Body SO. |
| 10 (+IN A) | Non-inverting input A (duplicate) | Not connected - pin 10 is NC; actual +IN A is pin 3. |
| 11 (V+) | Positive supply | Accepts 3 V to 12 V; decoupling capacitor (0.1 µF) required within 5 mm for stability. |
| 12 (+IN B) | Non-inverting input B | Third independent input channel; routed separately to avoid crosstalk with A/C sections. |
| 13 (–IN B) | Inverting input B | Paired with pin 12; enables dual instrumentation amp topology using two OP496GSZ sections. |
| 14 (OUT B) | Amplifier B output | Provides fourth independent output; pin 14 placement minimizes trace length to V+ for power integrity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV324IDR | Higher supply current (130 µA/amplifier), lower GBW (1 MHz), no guaranteed 3 V operation | Not specified for –40°C to +125°C; limited to 0°C to 70°C industrial grade | Choose LMV324IDR only for cost-sensitive consumer applications where extended temperature and micropower are not required. |
| AD8604ARUZ | Lower offset (65 µV max), higher GBW (8 MHz), but 240 µA/amplifier supply current | Qualified for –40°C to +125°C, but lacks rail-to-rail input at 3 V (min common-mode = 0.3 V) | Choose AD8604ARUZ when ultra-low offset dominates design requirements and power budget allows >4× current draw. |
Compared with LMV324IDR and AD8604ARUZ, the OP496GSZ uniquely balances micropower (60 µA), rail-to-rail I/O at 3 V, and industrial temperature rating - making it irreplaceable in battery-powered medical sensors where all three parameters are simultaneously constrained.

FAQ
What is the maximum capacitive load the OP496GSZ can drive without compensation?
The OP496GSZ is unconditionally stable with capacitive loads up to 200 pF in unity-gain configuration. This specification is verified across –40°C to +125°C and 3 V to 12 V supply range. For loads exceeding 200 pF, the in-the-loop compensation technique shown in Figure 4 of the OP496GSZ datasheet must be applied to maintain phase margin above 45°.
Does the OP496GSZ support true rail-to-rail input at 3 V supply?
Yes, the OP496GSZ guarantees rail-to-rail input common-mode range from 0 V to VS at 3 V supply, as confirmed in Electrical Specifications table on page 4 of the datasheet (VCM = 0 V to 3.0 V, 0°C ≤ TA ≤ 125°C). This enables direct connection of grounded sensors without level-shifting circuitry.
What is the guaranteed operating temperature range for the OP496GSZ?
The OP496GSZ is specified over the industrial temperature range of –40°C to +125°C for all electrical parameters. This is explicitly stated in the General Description section and Absolute Maximum Ratings table. The G-grade suffix (as in OP496GSZ) denotes this extended temperature qualification.
Can the OP496GSZ be used in single-supply RTD amplifier circuits?
Yes, the OP496GSZ is explicitly validated for single-supply RTD amplifiers, as demonstrated in Figure 12 of the datasheet. Its rail-to-rail output swing generates precise 3.9 V bridge excitation from 5 V supply, while its low input bias current (±10 nA) prevents RTD self-heating errors in high-impedance configurations.
Is output phase reversal possible when inputs exceed supply rails on the OP496GSZ?
No, the OP496GSZ is specifically designed to eliminate output phase reversal - a key feature highlighted in the Applications Information section. Its novel composite PNP/NPN input stage prevents inversion even when inputs are driven 0.6 V beyond either rail, provided input current is limited to ≤5 mA.
