Product details
Overview
TS932BIN from STMicroelectronics is a dual rail-to-rail output micropower operational amplifier in SO-8 package, designed for low-voltage single-supply operation (2.7 V to 10 V), delivering 2.95 V output swing at 3 V supply with 20 μA per amplifier quiescent current and 2 mV max input offset voltage (TS932B grade). It serves as a precision signal conditioning front-end in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TS932BIN datasheet, TS932BIN pinout, TS932BIN application, or TS932BIN equivalent, key selection criteria include rail-to-rail output capability under 3 V supply, ultra-low 1 pA input bias current for high-impedance pH electrode or photodiode amplification, micropower consumption for multi-year coin-cell operation, and automotive-grade temperature range (-40 °C to +105 °C) compliance.
Technical Context
The TS932BIN implements CMOS input stage architecture enabling 1 pA typical input bias current and rail-to-rail output swing down to 10 mV above VCC− and within 50 mV of VCC+ at 100 kΩ load. Its 100 kHz gain-bandwidth product and 50 V/ms slew rate support DC-coupled sensor buffering and slow analog signal chains without stability issues.
It operates across full industrial temperature range (−40 °C to +105 °C) with guaranteed 2 mV max input offset voltage (TS932B variant), 3 μV/°C offset drift, and 85 dB common-mode and supply rejection - critical for accurate measurement in noisy automotive or portable environments where supply rails fluctuate.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - enables direct operation from single Li-ion, two alkaline, or regulated 3.3 V/5 V rails without LDO overhead. |
| Quiescent Current | 20 μA per amplifier - supports >10-year battery life in smoke detectors or wireless sensor nodes with 200 mAh coin cells. |
| Input Offset Voltage | 2 mV max (TS932B) - ensures ≤0.2% error in 1 V full-scale pH meter or digital scale bridge amplifier outputs. |
| Input Bias Current | 1 pA typical - prevents >100 MΩ source impedance loading in electrochemical sensor or piezoelectric transducer interfaces. |
| Output Swing | 2.95 V at VCC = 3 V, RL = 100 kΩ - delivers >98% of rail-to-rail dynamic range for ADC input optimization in 3 V systems. |
| Gain-Bandwidth Product | 100 kHz - sufficient for anti-aliasing filtering and DC-stable sensor signal conditioning up to ~10 kHz bandwidth. |
| Common-Mode Rejection | 85 dB - rejects coupled noise from shared ground paths in automotive body control modules or industrial I/O cards. |
Pinout & Package
TS932BIN is housed in an 8-pin SOIC (SO-8) package with 1.27 mm pitch, 4.9 mm × 6.0 mm body size, and ECOPACK® RoHS-compliant finish. Thermal resistance θJA is 125 °C/W, supporting operation up to +105 °C ambient without forced cooling.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amplifier 1) | High-impedance node accepting differential signal; requires guarding for <1 pA leakage paths in pH probe circuits. |
| 2 | Non-inverting Input (Amplifier 1) | Reference or sensor connection point; matched layout critical to minimize thermal EMF-induced offset drift. |
| 3 | Output (Amplifier 1) | Rail-to-rail capable driver; directly interfaces 12-bit SAR ADCs with no level-shifting components needed. |
| 4 | VCC− (Ground) | Power return path; must be star-connected to minimize ground bounce in dual-amplifier configurations. |
| 5 | VCC+ (Supply) | Positive rail input; decoupling capacitor (100 nF X7R) required within 3 mm for stable 100 kHz GBW operation. |
| 6 | Non-inverting Input (Amplifier 2) | Independent second channel input; enables dual-sensor monitoring (e.g., temperature + humidity) in same footprint. |
| 7 | Inverting Input (Amplifier 2) | Second differential input; layout symmetry with Pin 1 reduces inter-channel crosstalk below −80 dB. |
| 8 | Output (Amplifier 2) | Second rail-to-rail output; supports simultaneous dual-channel signal conditioning without external multiplexing. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers usable 2.95 Vpp output at 3 V supply, maximizing dynamic range into 12-bit ADCs without external level shifters. |
| Ultra-low input bias current (1 pA) | Enables direct connection to high-impedance sources like glass pH electrodes (>1 GΩ) without significant DC error. |
| Micropower operation (20 μA/amplifier) | Reduces total system standby current to <50 μA for dual-channel designs, extending CR2032 battery life beyond 5 years. |
| Automotive-grade temperature range | Guaranteed operation from −40 °C to +105 °C meets AEC-Q100 stress test requirements for under-hood sensors. |
| ESD protection (2 kV HBM) | Withstands handling and board assembly ESD events without latch-up or parameter shift, reducing field failure risk. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358IDR | Higher 80 μA supply current, 7 mV max offset, no guaranteed 1 pA bias current - CMOS inputs but not optimized for ultra-high-Z sources. | Acceptable for general-purpose 3.3 V sensor buffering where battery life >2 years is sufficient and source Z <100 MΩ. | Select when cost sensitivity outweighs micropower or ultra-low bias requirements; verify layout for 80 μA thermal rise in sealed enclosures. |
| MCP6022-I/SN | Lower 100 μA supply current, 250 μV max offset, 1 pA bias current, but only rated to +85 °C - lacks automotive temperature range. | Suitable for commercial portable instruments (e.g., medical glucose meters) requiring higher DC precision but no under-hood operation. | Choose for sub-mV offset-critical applications below +85 °C; avoid in automotive or industrial environments exceeding 85 °C ambient. |
Compared with LMV358IDR and MCP6022-I/SN, TS932BIN uniquely combines automotive-grade temperature range, 2 mV max offset, and 1 pA bias in a micropower SO-8 package - making it the only option for long-life, high-impedance sensor conditioning in extended-temperature environments.

FAQ
What is the maximum operating supply voltage for TS932BIN?
The absolute maximum supply voltage is 12 V, but the recommended operating range is 2.7 V to 10 V per the datasheet's Table 3. Operation above 10 V risks exceeding internal junction limits and invalidates parametric guarantees, especially offset voltage and CMRR performance.
Does TS932BIN support true rail-to-rail input common-mode range?
No - TS932BIN features rail-to-rail *output* swing only. Its common-mode input voltage range is specified as VCC− − 0.2 V to VCC+ − 1.5 V (Table 3), meaning it cannot accept signals within 1.5 V of the positive rail. This is typical for CMOS-input op-amps with P-channel input pairs.
Can TS932BIN drive capacitive loads directly?
Stability is guaranteed for CL ≤ 50 pF per Figure 13–14. Driving larger capacitive loads (e.g., >100 pF cables or ADC input capacitance) requires isolation resistor (≥100 Ω) in series with the output to prevent peaking or oscillation, as phase margin drops below 65° at higher capacitance.
Is TS932BIN pin-compatible with other dual op-amps in SO-8?
TS932BIN follows standard SO-8 dual op-amp pinout (Pin 1: In− A, Pin 2: In+ A, Pin 3: Out A, Pin 4: V−, Pin 5: V+, Pin 6: In+ B, Pin 7: In− B, Pin 8: Out B), matching industry convention used by LM358, TL072, and MCP6022 - enabling drop-in replacement where electrical specs align.
