Product details
Overview
TSV914IPT 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, 4.5 V/µs slew rate, 1.1 mA max supply current per channel, and operates from 2.5 V to 5.5 V. Its 1 pA typical input bias current and 1.5 mV max input offset voltage (A grade) make it suitable for precision sensor interfaces in portable medical instrumentation.
For engineers reviewing the TSV914IPT datasheet, TSV914IPT pinout, TSV914IPT application, or TSV914IPT equivalent, key selection criteria include rail-to-rail operation at 2.5 V, unity-gain stability with capacitive loads up to 100 pF, ultra-low input bias current for high-impedance sources, and AEC-Q100 qualified variants for automotive signal conditioning.
Technical Context
The TSV914IPT implements a CMOS input stage enabling 1 pA typical input bias current and rail-to-rail input common-mode range (VCC− − 0.1 V to VCC+ + 0.1 V). Its internal compensation ensures unity-gain stability without external components while supporting 35 mA output drive capability into resistive loads.
It features 820 µA typical quiescent current per amplifier, 8 MHz gain-bandwidth product at 5 V, and maintains ≥45° phase margin with 100 pF capacitive load - critical for active filtering and battery-powered signal chains where power efficiency and stability coexist.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 8 MHz - enables stable closed-loop operation up to ~1 MHz with gain ≥1, suitable for anti-aliasing and reconstruction filters. |
| Supply voltage range | 2.5 V to 5.5 V - supports direct interface with Li-ion (3.0–4.2 V), USB (5 V), and low-dropout regulator outputs. |
| Input bias current | 1 pA typ. - minimizes voltage error in high-impedance sensor nodes (e.g., pH electrodes, photodiode transimpedance stages). |
| Input offset voltage | 1.5 mV max (A grade) - ensures ≤0.3% full-scale error in 0.5 V reference-based 12-bit ADC front-ends. |
| Slew rate | 4.5 V/µs - supports 10 kHz full-power bandwidth for 10 Vpp signals, adequate for ECG and pulse oximetry analog paths. |
| Output drive | ±35 mA - drives 600 Ω loads directly, eliminating need for external buffer stages in DAC output conditioning. |
| ESD protection | ≥5 kV HBM - meets IEC 61000-4-2 Level 3 for handheld device touchpoints and exposed analog inputs. |
Pinout & Package
TSSOP-14 package: 4.9 mm × 6.4 mm × 1.05 mm body, 0.65 mm pitch, exposed pad not internally connected (may be tied to VCC− or left floating).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Output (Out1–Out4) | Rail-to-rail sourcing/sinking outputs; each capable of ±35 mA into 600 Ω at 5 V. |
| 2, 6, 10, 14 | Inverting input (In1−–In4−) | High-impedance CMOS node; 1 pA bias current enables >1 GΩ source impedance interfacing. |
| 3, 7, 11, 12 | Non-inverting input (In1+–In4+) | Full rail-to-rail common-mode range (VCC− −0.1 V to VCC+ +0.1 V) allows direct connection to single-supply sensors. |
| 4 | VCC− (GND) | Power return; decoupling capacitor (10 nF) must be placed adjacent to this pin for stability. |
| 8 | VCC+ | Positive supply; accepts 2.5–5.5 V; internal regulation ensures consistent GBP across voltage range. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in single-supply systems (e.g., 3.3 V microcontroller ADC references). |
| Unity-gain stable with 100 pF load | Eliminates need for external compensation in active filter designs using ceramic output capacitors. |
| Low input offset drift | 5 µV/°C - limits thermal-induced error to <60 µV over −40 °C to 125 °C, critical for automotive cabin sensors. |
| High CMRR | 82 dB min at 5 V - rejects power supply ripple and common-mode noise in noisy industrial environments. |
| Latch-up immunity | 200 mA - prevents destructive failure during transient overvoltage events on input pins. |
Applications
| Portable ECG Monitor | Battery-Powered Gas Sensor |
|---|---|

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 |
|---|---|---|---|
| TSV994IPT | Higher GBP (20 MHz), higher ICC (1.5 mA/ch), same 1 pA Iib, but reduced CMRR (75 dB min). | Better for wideband active filters (>100 kHz), less suitable for DC-critical sensor bridges due to lower CMRR. | Select when bandwidth >10 MHz is required and supply current budget allows +0.4 mA/ch. |
| LMV324IPWR | Lower GBP (1 MHz), higher Iib (100 nA), wider VCC (2.7–5.5 V), no AEC-Q100 variant. | Cost-optimized for non-automotive consumer devices; insufficient for high-Z pH or photodiode sensors. | Choose only for cost-sensitive, non-precision, non-automotive applications with bandwidth <100 kHz. |
Compared with TSV914IPT, TSV994IPT trades higher power for bandwidth headroom in dynamic signal paths, while LMV324IPWR sacrifices precision and automotive compliance for lower BOM cost in undemanding applications.

FAQ
What is the maximum capacitive load the TSV914IPT can drive without external compensation?
The TSV914IPT is unity-gain stable and can drive up to 100 pF capacitive load directly without oscillation, as verified in the datasheet's phase margin vs. capacitive load curves (Figure 10). For loads exceeding 100 pF, a small series resistor (e.g., 10–50 Ω) at the output restores stability - design validation via bench testing and SPICE simulation is recommended.
Does the TSV914IPT support true single-supply operation with input voltages down to ground?
Yes. The TSV914IPT features rail-to-rail input with a common-mode range extending to VCC− − 0.1 V, allowing direct interface with grounded sensors (e.g., thermistors, strain gauges) when VCC− = 0 V. Its output also swings within 15 mV of both rails under 10 kΩ load, enabling full utilization of ADC reference voltage.
How does the A-grade (TSV914AIPT) differ from the standard TSV914IPT in production test?
The A-grade variant guarantees maximum input offset voltage of 1.5 mV at 25 °C (vs. 4.5 mV for standard grade) and 3 mV over −40 °C to 125 °C, with tighter distribution shown in Figure 2–3 of the datasheet. Both grades share identical AC performance, supply current, and package options - A-grade is selected for DC-critical applications like precision weigh scales or medical calibration circuits.
Can the exposed thermal pad on the TSSOP-14 package be connected to PCB ground?
No - the exposed pad of the TSV914IPT's TSSOP-14 package is not internally connected to any die node. Per datasheet Section 6.5, it may be left floating or tied to VCC− (ground in single-supply configurations) solely for mechanical anchoring and thermal conduction. Connecting it to PCB ground risks unintended coupling if nearby traces carry switching noise.
