Product details
Overview
OP496GSZ-REEL7 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 offset voltage, 60 µA per amplifier supply current, and operates from 3 V to 12 V single supply - enabling precision low-power analog front-ends in portable medical devices and industrial monitoring systems.
For engineers reviewing the OP496GSZ-REEL7 datasheet, OP496GSZ-REEL7 pinout, OP496GSZ-REEL7 application, or OP496GSZ-REEL7 equivalent, key selection considerations include guaranteed rail-to-rail swing at 3 V, industrial temperature range (–40°C to +125°C), 14-lead SOIC package compatibility, and verified stability with capacitive loads up to 200 pF without external compensation.
Technical Context
The OP496GSZ-REEL7 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 voltage gain and 26 nV/√Hz input voltage noise density.
Designed for single-supply operation, it eliminates phase reversal under overvoltage conditions and supports stable unity-gain configurations. The device handles capacitive loads ≤200 pF without oscillation and features no internal offset nulling pins - unlike the OP196 - confirming its fixed-offset, production-optimized design.
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, suitable for anti-aliasing and sensor signal conditioning. |
| Supply Current per Amplifier | 60 µA - allows four independent channels to operate from a 250 µA total budget, critical for multi-sensor battery-powered nodes. |
| Input Offset Voltage (max) | 300 µV - ensures ≤0.3% error in 100 mV full-scale sensor outputs without trimming. |
| Output Swing (low, IL = –1 mA) | 550 mV above V– - supports direct interfacing to 3.3 V ADC references when V– = GND. |
| Common-Mode Input Range | 0 V to 12 V - accepts inputs from ground to supply rail, eliminating level-shifting in single-supply bridge circuits. |
| Voltage Noise Density | 26 nV/√Hz at 1 kHz - preserves SNR in low-frequency (<10 kHz) biosignal amplification paths. |
| Operating Temperature Range | –40°C to +125°C - qualified for under-hood automotive and industrial control environments. |
Pinout & Package
The OP496GSZ-REEL7 is housed in a 14-lead narrow-body SOIC (SOIC_N) package compliant with JEDEC MS-012-AA, with 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 external load; rail-to-rail swing supports direct connection to SAR ADC inputs. |
| 2 (–IN A) | Inverting input A | Differential node for transducer interfaces; high CMRR (65 dB) rejects supply ripple. |
| 3 (+IN A) | Non-inverting input A | Accepts signals from 0 V to V+; enables ground-referenced sensor biasing. |
| 4 (V–) | Negative supply | Typically connected to GND in single-supply systems; sets lower rail for all four amplifiers. |
| 5 (+IN C) | Non-inverting input C | Independent input for third channel; shares V–/V+ rails but has dedicated I/O. |
| 6 (–IN C) | Inverting input C | Supports differential configuration with +IN C for RTD bridge sensing per Figure 12. |
| 7 (OUT C) | Amplifier C output | Used in instrumentation amplifier stages; drives gain-setting resistors without level shift. |
| 8 (OUT A) | Amplifier A output (duplicate) | Not applicable - pin 8 is OUT A (confirmed by SOIC pinout diagram); no duplicate assignment. |
| 9 (–IN A) | Inverting input A (duplicate) | Not applicable - pin 2 is –IN A; pin 9 is not assigned in 14-lead SOIC pinout. |
| 10 (+IN A) | Non-inverting input A (duplicate) | Not applicable - pin 3 is +IN A; pin 10 is not assigned in 14-lead SOIC pinout. |
| 11 (V+) | Positive supply | Single 3–12 V rail powers all four amplifiers; PSRR = 85 dB suppresses supply noise. |
| 12 (+IN B) | Non-inverting input B | Enables independent channel for reference buffering or DAC output conditioning. |
| 13 (–IN B) | Inverting input B | Paired with +IN B for active filtering or summing applications. |
| 14 (OUT B) | Amplifier B output | Provides second independent output; used in dual-channel current monitors (e.g., Figure 11). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Higher supply current (220 µA/amplifier), lower GBW (6.4 MHz), wider offset range (2 mV max). | Targeted at higher-speed, less power-constrained designs; not suitable for sub-100 µA battery nodes. | Select TLV2464IDR only when >1 MHz bandwidth is required and supply current budget exceeds 200 µA per channel. |
| AD8604ARUZ | Lower offset (65 µV max), higher GBW (8 MHz), higher supply current (240 µA/amplifier), TSSOP-14 package. | Optimized for precision instrumentation requiring <100 µV offset; consumes 4× more current than OP496GSZ-REEL7. | Choose AD8604ARUZ when offset-critical applications (e.g., weigh scales) demand <100 µV error, accepting higher power cost. |
Compared with TLV2464IDR and AD8604ARUZ, OP496GSZ-REEL7 uniquely balances ultra-low power (60 µA), rail-to-rail operation, and industrial temperature rating - making it the only option among the three qualified for extended-life battery systems operating from –40°C to +125°C with sub-100 µA per channel budgets.

FAQ
What is the maximum capacitive load the OP496GSZ-REEL7 can drive without external compensation?
The OP496GSZ-REEL7 is unconditionally stable with capacitive loads up to 200 pF in unity-gain configuration, as confirmed in the General Description and Applications Information sections. This enables direct interface to typical 10–50 pF ADC input capacitances and short PCB traces without added compensation networks.
Does the OP496GSZ-REEL7 have offset nulling pins like the OP196?
No, the OP496GSZ-REEL7 does not include offset nulling terminals. Unlike the OP196, which provides dedicated NULL pins, the OP496GSZ-REEL7 uses a fixed-offset design with guaranteed 300 µV max VOS - simplifying layout and eliminating potentiometer drift concerns in production systems.
Can the OP496GSZ-REEL7 operate from a 3 V supply while maintaining full rail-to-rail input range?
Yes, the OP496GSZ-REEL7 guarantees rail-to-rail input voltage range (0 V to V+) and rail-to-rail output swing down to 3 V supply, as specified in the Electrical Specifications table for VS = 3.0 V and confirmed in the General Description. At 3 V, VOH ≥ 2.85 V and VOL ≤ 70 mV at 100 µA load.
What is the thermal resistance (θJA) of the OP496GSZ-REEL7 in its 14-lead SOIC package?
The OP496GSZ-REEL7 in 14-lead SOIC package has a junction-to-ambient thermal resistance (θJA) of 120°C/W, as documented in the Absolute Maximum Ratings table. This value assumes standard JEDEC 2S2P test board conditions and is critical for calculating junction temperature rise under 240 µA total quiescent power dissipation.
Is the OP496GSZ-REEL7 pin-compatible with other members of the OP196 family such as the OP296?
No, the OP496GSZ-REEL7 is not pin-compatible with the OP296 or OP196 due to differing channel counts and pinouts: OP496 uses 14-lead SOIC with dedicated pins for four independent amplifiers, while OP296 uses 8-lead SOIC for two channels. Direct replacement requires PCB redesign and netlist updates.
