Product details
Overview
TSV912IDT from STMicroelectronics is a dual rail-to-rail input/output operational amplifier optimized for low-voltage, low-power applications. It delivers 8 MHz gain-bandwidth, 4.5 V/μs slew rate, and 1.1 mA max supply current per channel across 2.5–5.5 V operation, with 1.5 mV max input offset voltage (A grade) and 1 pA typical input bias current. It is used in precision sensor interfaces and battery-powered medical instrumentation.
For engineers reviewing the TSV912IDT datasheet, TSV912IDT pinout, TSV912IDT application, or TSV912IDT equivalent, key selection criteria include rail-to-rail I/O swing at 2.5 V supply, ultra-low input bias current for high-impedance sources, unity-gain stability with capacitive loads up to 100 pF, and AEC-Q100-compliant variants for automotive signal conditioning.
Technical Context
The TSV912IDT implements a CMOS input stage enabling 1 pA typical input bias current and rail-to-rail common-mode input range (VCC− − 0.1 V to VCC+ + 0.1 V), paired with a robust output stage delivering ±35 mA drive capability. Its 8 MHz GBP and 45° phase margin ensure stable unity-gain operation without external compensation.
It operates over −40 °C to +125 °C with supply rejection of 70–86 dB and common-mode rejection of 62–82 dB (at 5 V), supporting precision DC-coupled amplification in noisy industrial and automotive environments where low-offset drift (5 μV/°C) and thermal stability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 8 MHz - enables stable AC-coupled filtering up to ~1 MHz at unity gain |
| Slew rate | 4.5 V/μs - supports 10 kHz full-scale sine output at 20 Vpp without distortion |
| Input offset voltage (max) | 1.5 mV (A grade) - ensures ≤150 μV error in 100× gain sensor front-ends |
| Supply current per channel | 1.1 mA max - allows dual op-amp operation on coin-cell or single Li-ion supplies |
| Input bias current (typ) | 1 pA - preserves signal integrity in pH, photodiode, and piezoelectric sensor interfaces |
| Rail-to-rail I/O | Supports full dynamic range utilization from 2.5 V to 5.5 V supply - eliminates level-shifting in portable systems |
| ESD protection | ≥5 kV HBM - reduces board-level ESD hardening requirements in handheld devices |
Pinout & Package
TSV912IDT is housed in a 14-lead SO8 (Small Outline) package with exposed pad not internally connected. Pin 1 is marked by notch or dot; device orientation follows JEDEC MS-012.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Channel 1 output | Capable of sourcing/sinking ±35 mA - drives 600 Ω loads directly |
| 2 (IN1−) | Channel 1 inverting input | CMOS input with 1 pA bias - requires guarded traces in high-Z sensor paths |
| 3 (IN1+) | Channel 1 non-inverting input | Accepts signals from VCC− − 0.1 V to VCC+ + 0.1 V - enables true single-supply operation |
| 4 (VCC−) | Negative supply / ground reference | Common return for both channels; exposed pad may be tied here for thermal improvement |
| 5 (VCC+) | Positive supply | 2.5–5.5 V range - compatible with LDO outputs and USB-powered systems |
| 6 (IN2+) | Channel 2 non-inverting input | Independent high-impedance node - supports differential or single-ended configurations |
| 7 (IN2−) | Channel 2 inverting input | Matched to IN1− for common-mode rejection in dual-channel instrumentation |
| 8 (OUT2) | Channel 2 output | Unity-gain stable - usable as buffer without external compensation |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full 0–5 V signal swing on 5 V supply - eliminates need for level shifters in ADC driver stages |
| Ultra-low input bias current (1 pA typ.) | Minimizes voltage error across >100 MΩ source impedances - critical for electrochemical and capacitive sensors |
| Unity-gain stable with 100 pF capacitive load | Permits direct driving of ADC input capacitance or long PCB traces without isolation resistor |
| Low input offset voltage drift (5 μV/°C) | Maintains <15 μV total drift over −40 °C to +85 °C - suitable for uncalibrated medical thermistor circuits |
| High output current (±35 mA) | Drives LED indicators, relays, or multiple downstream op-amps without external buffers |
Applications
| Portable ECG Monitor | Battery-Powered Gas Sensor |
|---|---|
|
Use Scenario: Amplifying microvolt-level biopotential signals from dry electrodes in a handheld cardiac monitor. IC Role / Device Role / Timing Role: Dual-channel instrumentation amplifier front-end: one channel for differential sensing, second for reference buffering. Use Value: 1 pA input bias prevents electrode polarization; rail-to-rail output drives 12-bit SAR ADC directly at 3.3 V supply. |

IC Role / Device Role / Timing Role: Dual op-amp performing active low-pass filtering and DC offset removal before multiplexed ADC conversion. Use Value: AEC-Q100 qualified variants (e.g., TSV912IYDT) support 125 °C ambient operation; 82 dB CMRR rejects ignition noise. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV912AIDT | Guaranteed 1.5 mV max Vos (vs. 4.5 mV max for standard TSV912IDT); otherwise identical specs and pinout | Required for uncalibrated precision measurement where initial offset must be bounded | Select when Vos-critical applications cannot accommodate post-fabrication trimming or software calibration |
| MCP6022-I/SN | Lower GBP (10 MHz), higher supply current (1.2 mA), no A-grade option; same SO8 footprint and rail-to-rail I/O | Less suitable for battery life–sensitive designs due to higher ICC; lacks guaranteed low-Vos variant | Choose only if legacy design reuse or Microchip ecosystem integration outweighs 0.1 mA/channel efficiency loss |
Compared with TSV912IDT, the TSV912AIDT provides tighter initial offset control without trade-offs in speed or power, while the MCP6022-I/SN offers marginally higher bandwidth at the cost of increased quiescent current and no low-offset guarantee - making the TSV912IDT optimal for cost-sensitive, battery-constrained precision analog front-ends.

FAQ
What is the maximum capacitive load the TSV912IDT can drive without external compensation?
The TSV912IDT is unity-gain stable and can drive up to 100 pF capacitive load directly at the output without oscillation, as verified in the datasheet's Figure 10 and Section 5.1. For loads exceeding 100 pF, a small series resistor (e.g., 10–50 Ω) between the output and load is recommended to maintain phase margin above 45°.
Does the TSV912IDT support operation at 2.3 V supply?
Yes - the TSV912IDT is specified for operation down to 2.3 V at 0 °C to 125 °C (Table 2), though full parametric guarantees (e.g., GBP, slew rate) apply from 2.5 V. At 2.3 V, gain-bandwidth remains ≥7.2 MHz and supply current drops to ~0.78 mA per channel, enabling ultra-low-voltage use in energy-harvesting systems.
Is the exposed pad on the SO8 package electrically connected?
No - the SO8 package used for TSV912IDT does not feature an exposed thermal pad. That feature applies only to DFN8 2x2 variants (e.g., TSV912IQ2T). The SO8 (order code IDT) has standard gull-wing leads; thermal dissipation relies on PCB copper area connected to pins 4 (VCC−) and 5 (VCC+).
How does the TSV912IDT perform in single-supply photodiode transimpedance applications?
With 1 pA typical input bias current and rail-to-rail input down to VCC− − 0.1 V, the TSV912IDT minimizes dark-current-induced errors in photodiode TIAs. Its 21 nV/√Hz input noise at 10 kHz and 82 dB CMRR suppress ambient light interference, while the 4.5 V/μs slew rate preserves pulse fidelity in PPG and laser pulse detection circuits.
