Product details
Overview
TSV6391AILT from STMicroelectronics is a single-channel, rail-to-rail input/output CMOS operational amplifier optimized for micropower, precision signal conditioning in battery-powered systems. It delivers 2.4 MHz gain bandwidth product at 60 µA supply current (5 V), supports 1.5–5.5 V operation, features 500 µV max offset voltage (A-grade), and operates across –40 °C to 125 °C for industrial sensor front-ends and portable medical devices.
For engineers reviewing the TSV6391AILT datasheet, TSV6391AILT pinout, TSV6391AILT application, or TSV6391AILT equivalent, key selection criteria include its guaranteed low-offset A-version specification, shutdown-free architecture (vs. TSV6390), SC70-5 package footprint, rail-to-rail swing with 63 mA output drive, and stability at gains ≥4 - critical for active filtering and low-voltage transducer interfaces.
Technical Context
The TSV6391AILT employs complementary PMOS/NMOS input pairs enabling true rail-to-rail input common-mode range (VCC− −0.1 V to VCC+ +0.1 V) without phase reversal. Its internal compensation ensures stability at closed-loop gains of −3 or ≥4 with 60° phase margin under 100 pF capacitive load conditions.
DC precision is enhanced by 1 pA typical input bias current, 2 µV/°C offset drift, and 80 dB min CMRR at 5 V. AC performance includes 1.1 V/µs slew rate and 60 nV/√Hz input noise at 1 kHz, enabling accurate amplification of low-level sensor signals while maintaining bandwidth efficiency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - enables direct interface with single-cell Li-ion, NiMH, or 3.3 V/5 V logic rails without level-shifting. |
| Quiescent Current | 60 µA typical at 5 V - extends battery life in always-on monitoring nodes; stable ±17% dispersion across temperature. |
| Gain Bandwidth Product | 2.4 MHz typical - supports >100 kHz closed-loop bandwidth in gain-of-10 configurations for fast sensor response. |
| Input Offset Voltage | 500 µV maximum (A-grade) - reduces DC error in precision bridge amplifier and thermocouple conditioning circuits. |
| Rail-to-Rail I/O | Input: (VCC− −0.1 V) to (VCC+ +0.1 V); Output: within 35 mV of rails at 10 kΩ load - maximizes dynamic range in low-voltage ADC driver stages. |
| Output Drive | ±63 mA at VCC = 5 V - directly drives 8 Ω loads or multiple CMOS inputs without external buffers. |
| ESD Robustness | 4 kV HBM - withstands handling and board-level ESD events in portable device assembly and field service. |
Pinout & Package
TSV6391AILT is packaged in SC70-5 (SOT323-5), a 1.8 × 2.1 mm, 0.65 mm pitch surface-mount package with exposed pad for thermal enhancement and space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (−) | Differential node for feedback network connection; high-impedance (1 pA bias) enables high-Z sensor interfacing. |
| 2 | Non-inverting Input (+) | Reference input for single-ended signal acquisition; rail-to-rail common-mode range supports ground-referenced sources. |
| 3 | Ground (VCC−) | Power return path; must be low-inductance connection to minimize noise coupling into sensitive input stage. |
| 4 | Output | Capable of sourcing/sinking ±63 mA; rail-to-rail swing allows full utilization of 12-bit ADC input range. |
| 5 | Supply (VCC+) | Positive supply pin; requires local 10 nF ceramic decoupling per ST recommendation to suppress high-frequency PSRR degradation. |
Key Features
| Feature | Design Value |
|---|---|
| Low Power Precision | 60 µA ICC with 500 µV max Vio - achieves 0.01% linearity in 12-bit systems without sacrificing bandwidth. |
| Rail-to-Rail Operation | Full input/output swing across 1.5–5.5 V - eliminates need for dual supplies in portable instrumentation and wearable biosensors. |
| High Output Current | 63 mA drive capability - directly interfaces with LED indicators, analog switches, or low-impedance filters without buffer stages. |
| Wide Temperature Range | –40 °C to 125 °C operation - qualified for under-hood automotive sensors and industrial motor control feedback loops. |
| Stable Gain Configuration | Guaranteed stability at gain ≥4 (non-inverting) or ≥−3 (inverting) - simplifies layout for active anti-aliasing filters and gain blocks. |
Applications
| Battery-Powered Sensor Node | Portable Medical Front-End |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision, low-power op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV6391ILT | Standard grade (3 mV max Vio vs. 500 µV for A-grade); otherwise identical electrical specs and SC70-5 package. | Suitable for cost-sensitive industrial controls where <0.1% DC accuracy is not required. | Select when offset-critical calibration is performed digitally or system-level tolerance permits higher Vio. |
| MCP6001T-E/OT | Lower GBP (1 MHz), higher Vio (1.5 mV), same 60 µA ICC and SC70-5 package; no guaranteed 125 °C operation. | Limited to commercial-temperature consumer electronics; insufficient for automotive or industrial ambient extremes. | Choose only for non-extended temperature applications where reduced bandwidth is acceptable and lower cost is prioritized. |
Compared with TSV6391AILT, TSV6391ILT trades guaranteed low offset for lower unit cost without altering power or bandwidth, while MCP6001T-E/OT sacrifices both precision and temperature range to meet entry-level budget targets - making the A-grade TSV6391AILT optimal for calibrated, wide-temperature embedded sensing.

FAQ
Does TSV6391AILT include a shutdown pin?
No. TSV6391AILT is a 5-pin device without shutdown functionality. The shutdown feature is exclusive to the TSV6390/TSV6390A variants (6-pin SC70-6/SOT23-6). This simplifies PCB layout and eliminates SHDN control logic but means power cycling is required for complete current reduction.
What is the minimum stable closed-loop gain for TSV6391AILT?
The TSV6391AILT is stable at non-inverting gains ≥4 or inverting gains ≥−3, as verified by 60° phase margin testing with 100 pF capacitive load. Gains below these thresholds risk oscillation and require external compensation or selection of unity-gain-stable alternatives like TSV630.
Can TSV6391AILT drive capacitive loads directly?
It can drive up to 100 pF capacitive loads stably at gains ≥4 without external compensation. For larger loads (>100 pF) or lower gains, isolation resistors (e.g., 10–100 Ω in series with output) are recommended to maintain phase margin and prevent peaking, per Figure 4–6 in the datasheet.
Is TSV6391AILT pin-compatible with other SC70-5 op amps?
Yes - it follows standard SC70-5 pinout (IN−, IN+, GND, OUT, VCC), matching industry conventions used by MCP6001, TS912, and LMV321. However, electrical behavior (gain stability, offset, drive strength) differs, so functional validation is required before drop-in replacement.
