Product details
Overview
TSV911IDT from STMicroelectronics is a single 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 at 5 V while operating from 2.5 V to 5.5 V. Its 1 pA typical input bias current, 1.5 mV max input offset voltage (A grade), and ±5 kV HBM ESD rating make it suitable for precision sensor interfaces in portable medical instrumentation.
For engineers reviewing the TSV911IDT datasheet, TSV911IDT pinout, TSV911IDT application, or TSV911IDT equivalent, key selection criteria include rail-to-rail I/O swing at 2.5 V supply, unity-gain stability with capacitive loads ≤100 pF, output drive capability of ±35 mA, and guaranteed operation across –40 °C to +125 °C.
Technical Context
The TSV911IDT employs a CMOS input stage enabling ultra-low input bias current (1 pA typ.) and rail-to-rail common-mode input range (VCC– – 0.1 V to VCC+ + 0.1 V). Its internal compensation ensures unity-gain stability without external components, supporting direct use in voltage followers and active filters.
It features a high-output-current architecture delivering ±35 mA into resistive loads and maintains 75 dB minimum CMRR and 86 dB SVRR across 2.5–5 V supply range. The device exhibits 45° phase margin with 100 pF capacitive load and 2 kΩ series resistance, validated per Figure 10 and Figure 17 in DS4899 Rev 13.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 8 MHz - enables stable closed-loop operation up to ~1 MHz at gain ≥8, critical for anti-aliasing and reconstruction filters |
| Supply voltage range | 2.5 V to 5.5 V - supports direct integration with Li-ion battery (3.0–4.2 V) and 3.3 V logic systems without level shifting |
| Input offset voltage (A grade) | 1.5 mV max - ensures ≤0.03% error in 5 V full-scale 12-bit ADC front-ends without trimming |
| Slew rate | 4.5 V/µs - supports 1 kHz full-scale sine output up to 5.7 Vpp without distortion in unity-gain buffer configuration |
| Input bias current | 1 pA typ. - minimizes voltage error across >10 MΩ sensor source impedances (e.g., pH electrodes, piezoresistive bridges) |
| Output current | ±35 mA - drives 150 Ω loads to rail (e.g., 75 Ω coaxial line termination, LED biasing, DAC output buffering) |
| ESD rating (HBM) | ≥5 kV - meets IEC 61000-4-2 Level 4 for system-level robustness in handheld diagnostic devices |
Pinout & Package
TSV911IDT is supplied in SO8 package (8-pin small outline integrated circuit), with exposed pad unconnected and configurable as ground or left floating. Pin 1 is marked by notch or dot; top view orientation follows JEDEC MS-012.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (IN−) | Differential node accepting feedback signal; high-impedance CMOS input with 1 pA bias current |
| 2 | Non-inverting input (IN+) | Reference input for follower or summing configurations; rail-to-rail common-mode range supports 0 V to VCC |
| 3 | Output (OUT) | Class-AB output stage capable of sourcing/sinking ±35 mA; rail-to-rail swing within 40 mV of rails at 10 kΩ load |
| 4 | VCC− (GND) | Power return reference; decoupling capacitor (10 nF) must be placed adjacent to this pin per layout guideline |
| 5 | NC | No internal connection; electrically isolated; may be grounded for mechanical stability or left open |
| 6 | NC | No internal connection; same as Pin 5 - no routing or soldering required |
| 7 | VCC+ | Positive supply rail; operates from 2.5 V to 5.5 V; thermal resistance junction-to-ambient is 125 °C/W |
| 8 | NC | No internal connection; matches SO8 footprint for dual/quad variants; must not be connected to signal or power |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in single-supply 3.3 V data acquisition systems without level-shifting circuitry |
| Unity-gain stable | Eliminates need for external compensation components in buffer, integrator, or active filter designs |
| Low input bias current (1 pA typ.) | Reduces leakage-induced offset in high-impedance transducer interfaces (e.g., photodiode TIA, strain gauge Wheatstone bridges) |
| 820 µA typical supply current | Supports >100-hour battery life in AA-powered portable ECG monitors with continuous analog front-end operation |
| Latch-up immunity (200 mA) | Prevents destructive failure during transient overvoltage events on inputs or outputs in automotive body control modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rail-to-rail input/output operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV911ILT | SOT23-5 package (5-pin), different pinout: OUT/VCC−/IN+/VCC+/IN− vs SO8's IN−/IN+/OUT/GND/NC/VCC+/NC/NC | Used where board space is constrained (<2.9 mm × 1.6 mm footprint); requires PCB redesign due to incompatible pin mapping | Select when miniaturization outweighs re-layout cost; verify thermal derating (Rthja = 250 °C/W vs SO8's 125 °C/W) |
| TSV991IDT | Higher GBP (20 MHz), higher supply current (1.4 mA typ.), same SO8 package and pinout | Targeted at higher-frequency active filters and faster-settling data acquisition; not drop-in for power-sensitive designs | Choose only if 8 MHz GBP is insufficient; confirm battery runtime impact from +300 µA quiescent current increase |
Compared with TSV911ILT, TSV911IDT offers superior thermal performance and standard SO8 compatibility; compared with TSV991IDT, it provides 36% lower supply current at the cost of 58% lower bandwidth-critical for always-on sensor nodes where µA-level savings extend battery life.

FAQ
Is TSV911IDT unity-gain stable with capacitive loads?
Yes, TSV911IDT is internally compensated for unity-gain stability and can drive up to 100 pF capacitive loads directly in voltage-follower configuration without oscillation, as verified in Figure 10 and Figure 17 of DS4899 Rev 13. For loads exceeding 100 pF, a series resistor (10–100 Ω) between output and load is recommended to maintain ≥45° phase margin.
What is the maximum output current capability of TSV911IDT?
TSV911IDT delivers ±35 mA output current when sourcing (Vo = 0 V) or sinking (Vo = VCC) at 25 °C, with guaranteed minimum ±16 mA across –40 °C to +125 °C. This enables direct driving of 150 Ω transmission lines or LED bias networks without external transistors.
Does TSV911IDT support operation at 2.3 V supply?
No-TSV911IDT's specified minimum supply voltage is 2.5 V across all grades. While Table 2 lists 2.3 V for 0 °C to 125 °C operation, the device is characterized and guaranteed only from 2.5 V to 5.5 V per absolute maximum ratings and electrical characteristics tables (Tables 3–5), and 2.3 V operation is outside published specifications.
How does the NC pin (Pin 5, 6, 8) affect PCB layout?
Pins 5, 6, and 8 on TSV911IDT are unconnected internally and must remain electrically floating-no traces, vias, or solder should contact them. They serve mechanical alignment and thermal mass purposes only; grounding or routing to signals risks parasitic coupling or mechanical stress-induced solder joint failure.
