Product details
Overview
TS932ID from STMicroelectronics is a dual rail-to-rail output micropower operational amplifier in SO-8 package, designed for low-voltage single-supply systems (2.7–10 V). It delivers 2.95 V high-level and 10 mV low-level output swing at 3 V supply with 100 kΩ load, consumes only 20 μA per amplifier, and features ultra-low input bias current (1 pA) and 2 mV max input offset voltage (TS932B grade), enabling precision sensing in battery-powered instrumentation.
For engineers reviewing the TS932ID datasheet, TS932ID pinout, TS932ID application, or TS932ID equivalent, key selection criteria include micropower operation under 3 V, rail-to-rail output capability with <50 mV saturation, CMOS input stage compatibility with high-impedance sensors, and automotive-grade temperature range (-40 to +105 °C) support.
Technical Context
The TS932ID implements a CMOS-input dual op-amp architecture optimized for micropower operation across wide supply (2.7–10 V) and temperature (-40 to +105 °C) ranges. Its rail-to-rail output stage achieves 2.99 VOH and 50 mVVOL at 5 V supply with 100 kΩ load, while maintaining 100 kHz gain-bandwidth product and 50 V/ms slew rate under same conditions.
Input stage design ensures 1 pA typical input bias current and 2 mV max input offset voltage (TS932B), with 3 μV/°C drift, enabling stable DC-coupled amplification in pH meters and digital scales. Common-mode rejection (85 dB) and supply rejection (85 dB) are specified over full operating range, supporting noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7–10 V single supply - enables direct integration into 3 V Li-ion or 5 V USB-powered systems without level-shifting. |
| Supply Current | 20 μA per amplifier (typ.) - extends battery life beyond 1 year in 10 μA-sleep-cycle portable smoke detectors. |
| Input Offset Voltage | 2 mV max (TS932B grade) - supports 12-bit accuracy in 3.3 V ADC front-ends without trimming. |
| Output Swing | Rail-to-rail: 2.95 VOH/10 mVVOL @ 3 V, 100 kΩ - preserves dynamic range in low-voltage sensor signal conditioning. |
| Input Bias Current | 1 pA typ. - prevents loading errors in >1 GΩ pH electrode or piezoelectric sensor interfaces. |
| Gain Bandwidth | 100 kHz @ RL = 100 kΩ, CL = 50 pF - sufficient for DC–10 kHz sensor amplification with phase margin ≥65°. |
| CMRR / PSRR | 85 dB (min) - rejects power supply ripple and common-mode noise in automotive body control modules. |
Pinout & Package
TS932ID is housed in an SO-8 (Small Outline-8) package with 1.27 mm pitch, 4.90 × 6.00 mm footprint, and 1.75 mm height, compliant with ECOPACK® environmental standards.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amplifier 1) | High-impedance CMOS node accepting differential signal from sensor bridge or transducer. |
| 2 | Non-inverting Input (Amplifier 1) | Accepts reference or buffered sensor signal; 1 pA bias current avoids error in high-Z sources. |
| 3 | Output (Amplifier 1) | Rail-to-rail capable output driving ADC input or filter network up to 100 kΩ load. |
| 4 | VCC− (Ground) | Power return for both amplifiers; must be low-impedance to maintain CMRR >85 dB. |
| 5 | VCC+ (Supply) | Single positive supply input (2.7–10 V); decoupling capacitor required within 1 cm. |
| 6 | Non-inverting Input (Amplifier 2) | Independent input for second channel; shares supply rails but has separate signal path. |
| 7 | Inverting Input (Amplifier 2) | Second differential input; matched offset and bias specs ensure channel-to-channel tracking. |
| 8 | Output (Amplifier 2) | Second rail-to-rail output; usable for dual-sensor readout or active filtering stages. |
Key Features
| Feature | Design Value |

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 supply current (80 μA), wider offset range (7 mV max), no automotive temp grade. | Limited to commercial-temp consumer electronics; unsuitable for automotive or long-life battery designs. | Choose when cost is primary constraint and 3 V operation with rail-to-rail output is still required. |
| MCP6022-E/SN | Lower offset (250 μV typ.), higher GBW (1 MHz), but 100 μA supply current and no AEC-Q100 qualification. | Better for higher-speed sensor interfaces but incompatible with >5-year battery life requirements. | Prefer for precision analog front-ends where speed outweighs power budget, e.g., medical pulse oximetry. |
Compared with LMV358IDR and MCP6022-E/SN, TS932ID uniquely balances ultra-low power (20 μA), automotive temperature range, and 2 mV max offset-making it optimal for safety-critical, long-duration battery systems where reliability trumps raw bandwidth.

FAQ
What is the maximum operating supply voltage for TS932ID?
The absolute maximum supply voltage is 12 V, but the recommended operating range is 2.7 V to 10 V per the datasheet. Operation above 10 V risks exceeding internal junction temperature limits and degrading long-term reliability, especially at elevated ambient temperatures.
Does TS932ID support true rail-to-rail input?
No - TS932ID features rail-to-rail *output* only. Its common-mode input voltage range is specified as VCC− −0.2 V to VCC+ −1.5 V, meaning the inputs cannot accept signals within 1.5 V of the positive rail. This limitation must be accounted for in single-supply non-inverting amplifier configurations.
Is TS932ID qualified for automotive applications?
Yes - TS932ID is rated for −40 °C to +105 °C operation and meets AEC-Q100 stress test requirements as documented in ST's ordering information table. The "ID" suffix denotes industrial/automotive-grade SO-8 packaging with enhanced process controls and screening.
Can TS932ID drive capacitive loads directly?
Stability is guaranteed for capacitive loads ≤50 pF per the datasheet's phase margin specification (65°). Driving larger capacitive loads (e.g., ADC input capacitance >100 pF) requires isolation via a series resistor (≥100 Ω) or external compensation to avoid oscillation and overshoot.
