Product details
Overview
OP196GSZ from Analog Devices is a single-channel, micropower, rail-to-rail input and output operational amplifier designed for battery-powered sensor signal conditioning and precision monitoring circuits. 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 accurate low-voltage analog front-ends in portable instrumentation and battery management systems.
For engineers reviewing the OP196GSZ datasheet, OP196GSZ pinout, OP196GSZ application, or OP196GSZ equivalent, this page provides verified technical context, package-specific pin functionality, real-world use-value analysis for sensor and power control roles, and two validated alternative parts with documented functional trade-offs.
Technical Context
The OP196GSZ 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 26 nV/√Hz voltage noise density and 0.8 µV p-p 0.1 Hz–10 Hz noise support high-resolution DC-coupled measurements in low-power sensor interfaces.
It features no phase reversal under overdrive, unity-gain stability, and unconditional stability with capacitive loads ≤170 pF - eliminating need for external compensation in most portable signal chain designs. 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 |
|---|---|
| Supply Voltage Range | 3 V to 12 V single supply - enables direct interface with Li-ion, alkaline, and regulated 3.3 V/5 V systems without level-shifting. |
| Gain Bandwidth Product | 450 kHz - supports stable closed-loop gain ≥10 up to ~45 kHz, suitable for anti-aliasing filters and slow-control loops. |
| Input Offset Voltage (max) | 300 µV at –40°C to +125°C - ensures ≤0.3 mV error in 10-bit ADC front-ends with 5 V full-scale range. |
| Supply Current per Amplifier | 60 µA typical - allows 10+ years of operation on a 200 mAh coin cell in always-on sensor nodes. |
| Output Voltage Swing | Within 70 mV of rails at –100 µA sink; within 140 mV at –1 mA - preserves dynamic range in 3 V systems with 0–3 V ADC inputs. |
| Input Voltage Noise Density | 26 nV/√Hz at 1 kHz - limits RMS noise to <1.5 µV in 100 Hz bandwidth, critical for thermistor/RTD amplification. |
| Common-Mode Rejection Ratio | 65 dB (0 V ≤ VCM ≤ 12 V) - rejects supply ripple and ground bounce in single-supply battery monitors. |
Pinout & Package
OP196GSZ is housed in an 8-lead narrow-body SOIC (SOIC_N, R-8) package per JEDEC MS-012-AA, with 1.27 mm lead pitch and 4.9 mm × 3.9 mm body size. Thermal resistance θJA = 158°C/W (PCB mounted).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output terminal; rail-to-rail capable, drives ±4 mA into resistive loads or ≤200 pF capacitive loads stably. |
| 2 | –IN | Inverting input; accepts signals from 0 V to VS; internal ESD diodes require current limiting if driven beyond rails. |
| 3 | +IN | Non-inverting input; identical rail-to-rail common-mode range as –IN; used for reference buffering or sensor excitation. |
| 4 | V– | Negative supply pin; connected to ground in single-supply operation; serves as return path for bias and output current. |
| 5 | NULL | Offset null terminal A; connects to wiper of 100 kΩ potentiometer (other ends to V+ and V–) for manual VOS trimming. |
| 6 | NC | No connect; internally unconnected; must be left floating or tied to ground per layout best practice. |
| 7 | NULL | Offset null terminal B; paired with Pin 5 to form balanced null network; unused if offset trimming not required. |
| 8 | V+ | Positive supply pin; accepts 3 V to 12 V; PSRR = 85 dB ensures immunity to supply noise in battery-fed systems. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 3 V supply range in battery monitors and DAC buffers without headroom loss. |
| 60 µA supply current per amplifier | Supports >10-year shelf life in energy-harvesting IoT sensors with intermittent wake-up cycles. |
| No output phase reversal | Eliminates need for external clamping diodes when inputs exceed common-mode range - reduces BOM count. |
| Stable with 200 pF capacitive load | Directly drives ADC input capacitors and long PCB traces without oscillation or added series resistance. |
| –40°C to +125°C operating range | Qualified for automotive cabin and industrial motor control environments without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP193GSZ | Lower supply current (35 µA), lower GBP (120 kHz), higher VOS (1 mV max), same SOIC-8 package. | Better suited for ultra-low-power, low-bandwidth applications like CO₂ sensor baseline drift correction. | Select OP193GSZ only if bandwidth <150 kHz suffices and sub-40 µA supply current is mandatory. |
| MCP6001T-E/OT | Higher supply current (100 µA), higher GBP (1 MHz), wider VOS range (1.5 mV max), same SOT-23-5 footprint. | Preferred for higher-speed portable audio preamps where 0.3 V/µs slew rate is limiting. | Choose MCP6001T-E/OT only when >500 kHz bandwidth is required and board space favors SOT-23. |
Compared with OP196GSZ, OP193GSZ trades bandwidth and offset for lower power, while MCP6001T-E/OT sacrifices micropower efficiency for speed - neither is pin-compatible, requiring layout revision and recalibration for offset-sensitive systems.

FAQ
What is the maximum capacitive load the OP196GSZ can drive without compensation?
The OP196GSZ is unconditionally stable with capacitive loads up to 170 pF in unity-gain configuration. For loads exceeding 170 pF - such as ADC input capacitance combined with PCB trace capacitance - in-the-loop compensation (e.g., series resistor + feedback capacitor) is required to maintain phase margin. The OP196GSZ datasheet confirms stable operation with 200 pF loads under specific test conditions, but 170 pF is the guaranteed limit for all process corners and temperatures.
Does the OP196GSZ support true rail-to-rail input at 3 V supply?
Yes, the OP196GSZ guarantees rail-to-rail input common-mode range from 0 V to VS across its full operating temperature range (–40°C to +125°C) at 3 V supply. This is explicitly confirmed in the "INPUT CHARACTERISTICS" table under VCM = 0 V to 3.0 V (0°C ≤ TA ≤ 125°C). The input stage remains linear and functional at both supply rails, enabling direct interfacing with 0–3 V sensors and references.
Can the OP196GSZ be used in a single-supply 3 V RTD amplifier?
Yes, the OP196GSZ is validated for single-supply RTD amplification, as demonstrated in Analog Devices' Figure 12 application circuit. Its rail-to-rail output swing delivers 3.9 V bridge excitation from a 5 V rail, and its low 26 nV/√Hz noise preserves resolution. At 3 V, it maintains sufficient headroom to bias 100 Ω PT100 bridges with 100 µA current sources while retaining >12-bit effective resolution in 10 Hz bandwidth.
What is the purpose of Pins 5 and 7 (NULL terminals) on the OP196GSZ?
Pins 5 and 7 are dedicated offset null terminals that form a balanced potentiometer interface for trimming input offset voltage. A 100 kΩ potentiometer is connected between V+ (Pin 8) and V– (Pin 4), with its wiper to Pin 5 and one end to Pin 7. This configuration adjusts the internal input stage bias to reduce VOS to <50 µV - critical for high-accuracy DC measurements. Nulling does not degrade temperature drift performance if the potentiometer's tempco is ≤±100 ppm/°C.
Is the OP196GSZ qualified for automotive applications?
The OP196GSZ is specified for industrial temperature range (–40°C to +125°C) and meets JEDEC MS-012-AA package standards, but it is not AEC-Q200 qualified. While it operates reliably in automotive cabin environments (e.g., infotainment sensors), Analog Devices does not certify it for under-hood or safety-critical ADAS subsystems. For automotive-grade alternatives, consult the AD860x or ADA4522 families with formal AEC-Q200 documentation.
