Product details
Overview
TSV6390ILT from STMicroelectronics is a micropower, rail-to-rail input/output single operational amplifier optimized for precision low-voltage operation. It delivers 2.4 MHz gain bandwidth at 60 µA supply current (5 V), supports 1.5–5.5 V supply, features 500 µV max offset voltage (A version), and includes active shutdown mode drawing just 5 nA typical. It is used in battery-powered sensor front-ends requiring stable DC accuracy and fast settling.
For engineers reviewing the TSV6390ILT datasheet, TSV6390ILT pinout, TSV6390ILT application, or TSV6390ILT equivalent, key selection criteria include shutdown logic compatibility (SHDN low = disable), SC70-6/SOT23-6 package footprint constraints, rail-to-rail output swing under 10 kΩ load, and minimum stable gain of –3 or +4.
Technical Context
The TSV6390ILT uses complementary PMOS/NMOS input stages enabling true rail-to-rail input common-mode range (VCC– – 0.1 V to VCC+ + 0.1 V) with no phase reversal. Its internal compensation ensures stability at closed-loop gains ≥ –3 (inverting) or ≥ +4 (non-inverting), achieving 60° phase margin with 100 pF capacitive load.
Shutdown control is TTL/CMOS-compatible: SHDN ≤ 0.5 V disables the amplifier, placing output in high-impedance state with 1 nA leakage; turn-off time is 30 ns (5 V), turn-on time is 300 ns. Input bias current is 1 pA typical, supporting high-impedance source interfacing without significant error.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - enables direct use with single-cell Li-ion (3.0–4.2 V), alkaline (1.5 V), or regulated 3.3 V/5 V rails |
| Quiescent Current | 60 µA typical at 5 V - extends battery life in always-on monitoring nodes (e.g., >10-year CR2032 operation at 1 Hz sampling) |
| Gain Bandwidth Product | 2.4 MHz typical - supports 10-bit ADC driving at ~200 kSPS with <0.1% gain error in unity-gain buffer configuration |
| Input Offset Voltage | 500 µV max (TSV6390A variant) - limits DC error to <0.01% of full-scale in 5 V-span sensor conditioning |
| Output Drive Capability | ±63 mA at 5 V - drives 80 Ω loads directly (e.g., coaxial cable termination, LED biasing) |
| Shutdown Current | 5 nA typical - reduces system standby power by >99.99% vs. active mode, critical for energy-harvesting systems |
| Input Bias Current | 1 pA typical - permits use with >1 GΩ source impedances (e.g., piezoelectric sensors, pH electrodes) |
Pinout & Package
TSV6390ILT is supplied in SOT23-6 package (3.05 mm × 1.75 mm × 1.3 mm, 0.95 mm pitch), optimized for space-constrained portable PCBs. Thermal resistance junction-to-ambient is 240 °C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN+) | Non-inverting input | Accepts rail-to-rail common-mode signals from –0.1 V to VCC+0.1 V; 1 pA bias current minimizes loading on high-Z sources |
| 2 (IN–) | Inverting input | Differential pair node; matched to IN+ for <500 µV offset; requires symmetrical layout to preserve CMRR >55 dB |
| 3 (V–) | Negative supply | Ground reference for single-supply operation; must be decoupled with 10 nF capacitor placed <2 mm from pin |
| 4 (SHDN) | Shutdown control | Active-low enable: ≤0.5 V disables amplifier; must not float - tie to V– or use pull-down resistor |
| 5 (OUT) | Amplifier output | Rail-to-rail swing: within 35 mV of V– or V+ under 10 kΩ load; capable of ±63 mA sourcing/sinking |
| 6 (V+) | Positive supply | Accepts 1.5–5.5 V; internal ESD protection rated to 4 kV HBM; requires local 10 nF decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in single-supply systems (e.g., 0–3.3 V ADC interface) without level-shifting circuitry |
| 60 µA quiescent current | Permits continuous operation from coin-cell batteries (e.g., CR2032) for >5 years in low-duty-cycle IoT endpoints |
| 500 µV max offset (A version) | Reduces calibration overhead in medical-grade temperature or pressure signal chains where <0.1°C/0.1%FS accuracy is required |
| 4 kV HBM ESD rating | Eliminates need for external transient protection in handheld device front-ends exposed to user handling |
| Stable at gain ≥ –3 or +4 | Allows direct use in transimpedance amplifiers (TIA) for photodiode current-to-voltage conversion without added compensation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision micropower op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV6391ILT | No shutdown pin; SOT23-5 package; same GBW, supply, and offset specs | Suitable where board area is constrained and shutdown is unnecessary (e.g., always-on sensor nodes) | Select when minimizing pin count and PCB footprint is prioritized over power gating capability |
| MCP6001T-I/OT | Higher 100 µA supply current; 1 MHz GBW; no shutdown; 2.7–5.5 V supply only | Limited to 2.7 V+ systems; lower bandwidth restricts use in >100 kHz active filters | Choose only if legacy design uses Microchip ecosystem and 1.5–2.6 V operation is not required |
Compared with TSV6391ILT, the TSV6390ILT adds shutdown control at no cost to bandwidth or offset performance, while MCP6001T-I/OT trades 40% higher current and 58% lower bandwidth for broader vendor support - making TSV6390ILT optimal for new 1.5 V–5.5 V battery designs needing active power management.

FAQ
What is the minimum recommended supply voltage for reliable TSV6390ILT operation?
The TSV6390ILT is fully specified and guaranteed from 1.5 V to 5.5 V. At 1.5 V, it maintains 2 MHz gain bandwidth, 60 µA supply current, and rail-to-rail input/output functionality. Operation below 1.5 V risks undefined behavior, including reduced output swing and increased offset drift - ST does not characterize or guarantee performance below this threshold.
Can the TSV6390ILT drive a 100 pF capacitive load without oscillation?
Yes, but only when configured with closed-loop gain ≥ –3 (inverting) or ≥ +4 (non-inverting). The datasheet confirms 60° phase margin under these conditions with 100 pF load and 10 kΩ resistive termination. Unity-gain or gain-of-2 configurations require external compensation (e.g., series R + small C at output) to prevent peaking or instability.
How does the shutdown function affect output state and leakage?
When SHDN is pulled ≤0.5 V, the amplifier output enters high-impedance state with ≤1 nA leakage current (typical) to either rail. Output remains floating - no internal clamping or pull-down. This allows safe multiplexing of multiple TSV6390ILT outputs onto a shared bus without contention, provided external pull resistors define idle state.
Is the TSV6390ILT pin-compatible with other ST micropower op-amps like TSV6290 or TSV630?
No. TSV6390ILT uses SOT23-6 pinout (IN+, IN–, V–, SHDN, OUT, V+), while TSV6290-1 and TSV630-1 use SOT23-5 (omitting SHDN). Pin mapping differs: TSV6390ILT pin 4 is SHDN, whereas TSV6290-1 pin 4 is V+. Direct replacement requires PCB redesign and firmware updates to manage shutdown control.
