Product details
Overview
TS932AIDT 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 high-level and 10 mV low-level output swing at 3 V supply with 100 kΩ load, 20 μA typical supply current per amplifier, and 2 mV max input offset voltage (TS932B grade). It serves signal conditioning in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TS932AIDT datasheet, TS932AIDT pinout, TS932AIDT application, or TS932AIDT equivalent, key selection criteria include rail-to-rail output swing under micropower constraints, ultra-low input bias current (1 pA), CMOS input stage compatibility with high-impedance sources, and automotive-grade temperature range (-40 °C to +105 °C) support.
Technical Context
The TS932AIDT integrates two independent CMOS-input op-amps with rail-to-rail output stages, enabling full dynamic range utilization in single-supply systems down to 2.7 V. Its input common-mode range extends from VCC− −0.2 V to VCC+ −1.5 V, supporting direct sensing of near-ground signals without level-shifting.
It achieves 100 kHz gain-bandwidth product and 50 V/ms slew rate while maintaining 65° phase margin into 50 pF capacitive loads, ensuring stable unity-gain follower operation. Input voltage noise is 75 nV/√Hz at 1 kHz, and ESD protection meets 2 kV HBM standard.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 10 V - enables direct use with Li-ion, alkaline, or regulated 3.3 V/5 V rails without external regulators |
| Supply Current (per amp) | 20 μA typ. - supports >1-year battery life in coin-cell–powered devices operating at 100% duty cycle |
| Input Offset Voltage | 2 mV max. (TS932B grade) - ensures ≤0.2% error in 1 V full-scale sensor amplification |
| Input Bias Current | 1 pA typ. - preserves signal integrity when interfacing pH electrodes or piezoresistive sensors with >1 GΩ source impedance |
| Output Swing (3 V supply) | 2.95 V high / 10 mV low into 100 kΩ - delivers >98% of rail-to-rail range for ADC input optimization |
| Gain-Bandwidth Product | 100 kHz - sufficient for DC-coupled sensor buffering and low-frequency filtering up to ~10 kHz |
| Common-Mode Rejection | 85 dB min. - rejects power supply ripple and shared-noise coupling in multi-sensor PCB layouts |
Pinout & Package
TS932AIDT is housed in an SO-8 (Small Outline-8) plastic package with 1.27 mm pitch, 4.9 mm × 6.0 mm body, and ECOPACK® environmental compliance. Pin 1 is marked by a notch or dot; top view orientation follows JEDEC MS-012.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input of Amp A | Accepts differential signal reference or feedback node; high-impedance CMOS input minimizes loading on preceding stage |
| 2 | Non-inverting input of Amp A | Connects to sensor output or reference voltage; 1 pA bias current avoids error in high-Z source applications |
| 3 | Output of Amp A | Drives ADC input or next-stage buffer; rail-to-rail swing maximizes SNR in 12-bit+ systems |
| 4 | VCC− (Ground) | Power return path; must be low-inductance connection to minimize PSRR degradation and oscillation risk |
| 5 | VCC+ (Supply) | Positive supply rail; decoupling capacitor (100 nF ceramic) required within 5 mm for stability |
| 6 | Non-inverting input of Amp B | Independent channel input; enables dual-sensor readout or signal + reference amplification |
| 7 | Inverting input of Amp B | Supports inverting configuration or feedback loop; identical electrical specs to Pin 1 |
| 8 | Output of Amp B | Second independent output; allows simultaneous processing of two analog channels without cross-talk |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output stage | Delivers usable signal headroom within 10 mV of both supply rails, eliminating need for negative supply in single-ended sensor front-ends |
| Micropower operation | 20 μA per amplifier enables continuous monitoring in energy-harvesting or battery-backed IoT nodes with multi-year runtime |
| CMOS input architecture | 1 pA input bias current prevents voltage error across high-impedance sources like thermistors, pH probes, or photodiode transimpedance feedback resistors |
| Automotive-grade temperature range | -40 °C to +105 °C operation validated per AEC-Q100 requirements, suitable for under-hood or cabin-mounted automotive sensors |
| ESD robustness | 2 kV HBM rating protects against handling damage during PCB assembly and field service without external clamping diodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Higher supply current (550 μA), wider GBW (6.4 MHz), but no automotive qualification | Better for higher-speed sensor interfaces (>10 kHz), unsuitable for long-life battery systems | Select when bandwidth >100 kHz is required and automotive temp range is not mandatory |
| MCP6022-I/SN | Lower offset (250 μV typ.), higher ICC (100 μA), non-automotive grade (-40 °C to +85 °C) | Improved DC precision for lab-grade instrumentation, limited thermal reliability in automotive environments | Prefer for cost-sensitive industrial sensors where extended temperature range is unnecessary |
Compared with TLV2462IDR and MCP6022-I/SN, TS932AIDT uniquely balances micropower consumption (20 μA), automotive-grade temperature range (-40 °C to +105 °C), and rail-to-rail output in a legacy-proven SO-8 footprint-making it optimal for safety-critical, battery-constrained, and thermally demanding embedded sensor nodes.

FAQ
Is TS932AIDT qualified for automotive applications?
Yes. TS932AIDT is manufactured and tested to AEC-Q100 Grade 2 standards (-40 °C to +105 °C), with full qualification documented in ST's official datasheet revision history and order code tables. It carries automotive-grade marking (e.g., "932AI" on tape-and-reel reels) and is approved for use in non-safety-critical cabin and chassis sensor modules.
What is the maximum capacitive load the TS932AIDT can drive stably?
The TS932AIDT maintains 65° phase margin with up to 50 pF capacitive load when configured as a unity-gain follower, as verified in Figure 13 of the datasheet. Driving >100 pF requires external isolation resistor (≥100 Ω) between output and load to prevent peaking or oscillation.
Can TS932AIDT operate from a 1.8 V supply?
No. The absolute minimum supply voltage is 2.7 V per Table 3 (Operating Conditions); operation below this risks undefined behavior, reduced output swing, and failure to meet specified offset or CMRR performance. For 1.8 V systems, consider ST's TSU102 or similar sub-2-V rail-to-rail op-amps.
Does TS932AIDT have internal ESD protection on all pins?
Yes. All input and output pins feature integrated 2 kV HBM ESD protection per IEC 61000-4-2 Level 2, confirmed in Table 2 (Absolute Maximum Ratings) and validated in ST's ECOPACK® reliability reports. No external TVS diodes are required for standard handling or board-level ESD immunity.
