Product details
Overview
TSV914ID from STMicroelectronics is a quad rail-to-rail input/output operational amplifier optimized for low-voltage, low-power applications. It delivers 8 MHz gain-bandwidth product, 4.5 V/µs slew rate, and 1.1 mA max supply current per channel at 5 V, with rail-to-rail swing enabling full dynamic range in 2.5–5.5 V systems. It is used in battery-powered medical instrumentation and portable signal conditioning circuits.
For engineers reviewing the TSV914ID datasheet, TSV914ID pinout, TSV914ID application, or TSV914ID equivalent, key selection criteria include its 1 pA typical input bias current, 1.5 mV max input offset voltage (A grade), 35 mA output drive capability, and SO14 package compatibility with industrial temperature range (−40 °C to +125 °C).
Technical Context
The TSV914ID implements a unity-gain-stable CMOS input stage with rail-to-rail input common-mode range (VCC− −0.1 V to VCC+ +0.1 V) and rail-to-rail output swing (within 15 mV of rails at 10 kΩ load). Its 8 MHz GBP and 45° phase margin ensure stable operation driving capacitive loads up to 100 pF without external compensation.
It features ultra-low input bias current (1 pA typ.) and low input offset drift (5 µV/°C), making it suitable for high-impedance sensor interfaces. The device maintains 75 dB minimum CMRR and 82 dB SVRR across 2.5–5 V supply, supporting precision DC-coupled amplification in portable and automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 8 MHz - enables stable unity-gain amplification up to audio frequencies with minimal phase lag |
| Slew rate | 4.5 V/µs - supports 1 kHz full-scale sine output up to ~1.4 Vpp without distortion |
| Supply current per channel | 0.78–1.1 mA - allows four op-amps to operate below 4.4 mA total at 5 V, ideal for battery life extension |
| Input offset voltage (A grade) | 1.5 mV max - ensures ≤0.03% error in 50 mV full-scale sensor signal amplification |
| Output drive current | ±35 mA - drives 150 Ω loads directly, eliminating need for external buffer stages |
| Common-mode rejection ratio | 62–82 dB - rejects power-supply noise and ground bounce in mixed-signal PCB layouts |

Use Scenario: Amplifying microvolt-level biopotential signals from dry electrodes in handheld cardiac monitors. IC Role / Device Role / Timing Role: Quad TSV914ID configures two channels as low-noise instrumentation amplifier front-end (In1±, In2±), one as reference buffer (In3±), and one as ADC driver (Out4 → SAR ADC). Use Value: 21 nV/√Hz input noise and 1.5 mV max offset preserve signal integrity over 0.05–150 Hz bandwidth while consuming <4.4 mA total. |
Use Scenario: Conditioning analog output from electrochemical CO sensors in portable air quality meters. IC Role / Device Role / Timing Role: One channel performs transimpedance conversion (In1−/Out1), second provides zero-drift baseline correction (In2+/Out2), third filters 50/60 Hz interference (Sallen-Key on In3±/Out3), fourth buffers final output (In4±/Out4). Use Value: 1 pA input bias prevents sensor polarization; rail-to-rail output drives 10-bit ADC input directly across 2.7–3.6 V battery range. |

Use Scenario: Signal conditioning for NDIR CO₂ and VOC sensors in vehicle HVAC control units operating at −40 °C to +105 °C.

Use Value: Guaranteed operation to 125 °C junction temperature and 75 dB CMRR suppress engine bay EMI without additional shielding. |
Use Scenario: Precision DC amplification and auto-ranging in 4½-digit handheld DMMs powered by alkaline batteries. IC Role / Device Role / Timing Role: Configured as programmable-gain amplifier (PGA) with In1±/Out1, comparator hysteresis generator (In2±/Out2), reference buffer (In3±/Out3), and autoranging switch driver (In4±/Out4). Use Value: 5 µV/°C offset drift minimizes calibration frequency; 82 dB SVRR rejects battery voltage sag during current measurement pulses. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV994IDT | Higher GBP (20 MHz), higher supply current (1.8 mA/ch), same 1 pA Ibias | Better for >100 kHz active filters; less suitable for sub-10 µA standby modes | Select when bandwidth >10 MHz is required and power budget allows +0.7 mA/ch increase |
| LMV324IDR | Lower GBP (1 MHz), higher Ibias (100 nA), wider supply (2.7–5.5 V), no A-grade option | Cost-optimized for non-precision consumer applications; lacks medical/automotive temp range | Select only for cost-sensitive, non-critical signal paths where offset <5 mV is acceptable |
Compared with TSV914ID, TSV994IDT trades 128% more bandwidth for 64% higher quiescent power, while LMV324IDR sacrifices 87.5% bandwidth and 100× input bias current for lower unit cost-making TSV914ID optimal for precision, low-power, wide-temp quad amplification.

FAQ
What is the maximum capacitive load the TSV914ID can drive without external compensation?
The TSV914ID is unity-gain stable and can drive up to 100 pF capacitive loads directly in follower configuration without oscillation, as verified in the datasheet's Figure 10 and Section 5.1. For loads exceeding 100 pF, a series resistor (10–100 Ω) between output and load is recommended to maintain phase margin above 45°.
Does the TSV914ID support true single-supply operation with input voltages down to ground?
Yes. The TSV914ID features rail-to-rail input stage with common-mode range extending from (VCC− −0.1 V) to (VCC+ +0.1 V). At VCC− = 0 V (ground), inputs accept signals from −0.1 V to VCC+ +0.1 V, enabling direct interfacing with grounded sensors and 0 V-referenced DACs without level-shifting circuitry.
How does the SO14 package of TSV914ID handle thermal dissipation in continuous 4-channel operation?
At 1.1 mA per channel and 5 V supply, total power dissipation is 22 mW. With SO14 RthJA = 103 °C/W, junction temperature rise is ~2.3 °C above ambient-well within safe limits. The dual VCC+/VCC− pins reduce package resistance, improving thermal uniformity across all four amplifiers during sustained output current delivery.
Is there a pin-compatible automotive-grade version of the TSV914ID?
Yes. TSV914IYDT is the AEC-Q100 qualified variant in SO14 package, rated for −40 °C to +125 °C operation with enhanced ESD robustness (5 kV HBM) and lot-to-lot parametric stability. It shares identical pinout, electrical specs, and footprint with TSV914ID, enabling drop-in replacement in automotive cabin and body-control modules.
