Product details
Overview
TSV914AIPT 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, 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 TSV914AIPT datasheet, TSV914AIPT pinout, TSV914AIPT application, or TSV914AIPT 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 qualified variants for automotive signal conditioning.
Technical Context
The TSV914AIPT 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), supporting direct interfacing with sensors and ADC references. Its 8 MHz GBP and 4.5 V/µs slew rate are achieved with only 1.1 mA per amplifier at 5 V, balancing speed and power efficiency.
It features unity-gain stable compensation, allowing use in follower, active filter, and transimpedance configurations without external compensation. The device maintains ≥45° phase margin with 100 pF capacitive load and includes internal ESD protection ≥5 kV HBM and latch-up immunity up to 200 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 8 MHz - supports closed-loop bandwidth up to ~7.2 MHz at unity gain for precision AC-coupled signal paths |
| Supply voltage range | 2.5 V to 5.5 V - enables direct operation from single-cell Li-ion (3.0–3.7 V) or 3.3 V/5 V system rails |
| Input offset voltage (A grade) | 1.5 mV max at 25 °C - ensures ≤0.3% error in 0.5 V full-scale sensor output amplification |
| Input bias current | 1 pA typ. - preserves signal integrity when driving from >1 GΩ source impedances (e.g., pH electrodes, photodiodes) |
| Output drive capability | ±35 mA - sustains 600 Ω load at rail-to-rail swing without clipping in active filtering stages |
| Common-mode rejection | 62–82 dB - rejects supply ripple and shared-noise coupling in mixed-signal PCB layouts |
| ESD rating (HBM) | ≥5 kV - meets IEC 61000-4-2 Level 3 for robustness in handheld and automotive assembly environments |
Pinout & Package
TSSOP-14 package: 4.9 mm × 6.4 mm × 1.05 mm body height, 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 drives ≥35 mA into 600 Ω while maintaining linearity |
| 2, 6, 10, 14 | Inverting input (In1−–In4−) | High-impedance CMOS node; 1 pA bias current minimizes DC error in precision integrators |
| 3, 7, 11, 12 | Non-inverting input (In1+–In4+) | Accepts signals from VCC− −0.1 V to VCC+ +0.1 V - enables true single-supply sensor biasing |
| 4 | VCC+ | Positive supply rail; decoupling capacitor (10 nF) required adjacent to pin for stability |
| 8 | VCC− | Negative supply rail (typically ground); exposed pad may be connected here for thermal relief |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization with 2.5 V supply - no headroom loss in portable data acquisition |
| Unity-gain stable | Eliminates need for external compensation in buffer, active low-pass, or differential receiver designs |
| Low input bias current (1 pA typ.) | Reduces voltage error across high-value feedback resistors (>1 MΩ) in transimpedance amplifiers |
| 820 µA typical supply current per channel | Supports four independent analog channels on <4 mA total - critical for multi-sensor wearables |
| Operating temperature: −40 °C to 125 °C | Validated performance across automotive under-hood and industrial ambient conditions |

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 |
|---|---|---|---|
| TSV994AIPT | Higher GBP (20 MHz), higher ICC (1.8 mA/ch), same 1 pA Iib and rail-to-rail I/O | Better suited for >100 kHz active filters or faster sensor sampling; less optimal for sub-1 mA battery life targets | Select when bandwidth >10 MHz is required and power budget allows +0.7 mA/ch overhead |
| MCP6004-E/ST | Lower GBP (1 MHz), higher Vos (3 mV max), 100 pA Iib, same supply range and package | Adequate for DC-coupled sensor buffering but insufficient for audio or fast step-response applications | Select for cost-sensitive, low-bandwidth (<100 kHz) industrial controls where ultra-low Iib is not critical |
Compared with TSV914AIPT, TSV994AIPT trades 120% higher bandwidth for 70% higher quiescent current, while MCP6004-E/ST reduces cost and power by 30% but sacrifices 5× input bias current and 8× gain-bandwidth - making TSV914AIPT the optimal balance for precision, low-power, mid-speed analog front-ends.

FAQ
What is the maximum capacitive load the TSV914AIPT can drive without external compensation?
The TSV914AIPT is unity-gain stable and can drive up to 100 pF capacitive load directly in voltage-follower configuration 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 output and load is recommended to maintain ≥45° phase margin.
Does the exposed pad on the TSSOP-14 package require connection?
No - the exposed pad on the TSV914AIPT's TSSOP-14 package is not internally connected. Per datasheet Section 6.5 and Figure 26, it may be soldered to VCC− (ground) for improved thermal dissipation or left electrically floating, with no impact on electrical performance or reliability.
How does the TSV914AIPT's input offset voltage drift compare to standard industrial op-amps?
The TSV914AIPT specifies ∆Vio/∆T = 5 µV/°C (max), significantly lower than typical general-purpose op-amps (e.g., LM324: 10–20 µV/°C). This low drift ensures <0.6 µV error over a 125 °C temperature span, critical for uncalibrated, wide-temperature industrial sensor nodes.
Can the TSV914AIPT operate reliably from a single 2.5 V lithium-thionyl chloride cell?
Yes - the TSV914AIPT is fully specified down to 2.5 V supply (Table 2), with rail-to-rail I/O enabling full 0–2.5 V output swing and 1.5 mV max Vos ensuring <0.06% gain error at 2.5 V. Its 820 µA typical ICC per channel supports multi-year operation in ultra-low-duty-cycle IoT sensor transmitters.
