Product details
Overview
TSV624IPT from STMicroelectronics is a quad rail-to-rail input/output CMOS operational amplifier optimized for ultra-low-power, low-voltage operation. It delivers 420 kHz gain bandwidth at 29 µA supply current per amplifier, operates from 1.5 V to 5.5 V, and features 1 pA typical input bias current and 800 µV max input offset voltage (A version), enabling precision signal conditioning in battery-powered medical sensors and portable instrumentation.
For engineers reviewing the TSV624IPT datasheet, TSV624IPT pinout, TSV624IPT application, or TSV624IPT equivalent, key selection criteria include its rail-to-rail I/O capability at sub-2-V supply, shutdown current of 5 nA typ, unity-gain stability with 100 pF capacitive load, and EMI-hardened performance up to 2.4 GHz - critical for noise-sensitive analog front-ends in compact, energy-constrained systems.
Technical Context
The TSV624IPT employs complementary PMOS/NMOS input stages to achieve rail-to-rail input common-mode range from (VCC−) −0.1 V to (VCC+) +0.1 V, with seamless transition at (VCC+) −0.7 V and guaranteed absence of phase reversal. Its output swings within 35 mV of both rails into a 10 kΩ load referenced to VCC/2.
It integrates an EMI-hardened architecture delivering 61–92 dB EMIRR across 400 MHz–2.4 GHz, and uses internal current trimming to constrain supply current variation to ±17% - ensuring consistent GBP (350–420 kHz min/typ), slew rate (0.12–0.19 V/µs), and large-signal gain (73–98 dB) across voltage and temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.5–5.5 V: Enables direct integration with single-cell Li-ion, coin-cell, or 3.3 V logic rails without LDO overhead. |
| Quiescent Current | 29 µA typ per op-amp: Supports >1-year battery life in always-on sensor nodes powered by CR2032 cells. |
| Gain Bandwidth | 420 kHz typ at 5 V: Sufficient for anti-aliasing, sensor amplification, and active filtering up to ~40 kHz. |
| Input Offset Voltage | 800 µV max (A version): Minimizes DC error in precision bridge sensor interfaces and medical ECG front-ends. |
| Input Bias Current | 1 pA typ: Preserves signal integrity in high-impedance pH, photodiode, or piezoelectric sensor circuits. |
| EMI Rejection Ratio | 92 dB at 1.8 GHz: Suppresses cellular/WiFi interference in wearable health monitors without external shielding. |
| Rail-to-Rail I/O | Input: (VCC−)−0.1 V to (VCC+)+0.1 V; Output: Within 35 mV of rails: Maximizes dynamic range in low-voltage ADC driver applications. |
Pinout & Package
TSSOP16 package: 5.0 mm × 4.4 mm × 1.05 mm body, 0.65 mm pitch, 16-pin thin shrink small outline package with exposed thermal pad (not electrically connected), RoHS-compliant and ECOPACK® certified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 7 | Inverting Input (−) | Differential input node for Op-Amp 1–4; accepts signals down to VCC− −0.1 V. |

| 9, 10, 12, 14 | Output | Amplified output capable of sourcing/sinking ≥40 mA and swinging within 35 mV of rails. |
| 11, 13 | Shutdown Control | SHDN3/4: Active-low logic inputs; pulling to VCC− disables Op-Amps 3 & 4, reducing ICC to 5 nA typ. |
| 15 | VCC+ | Positive supply rail (1.5–5.5 V); requires local 10 nF decoupling per datasheet layout guidance. |
| 16 | VCC− | Ground reference; must be tied to system GND; serves as logic low threshold for SHDN pins. |

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 |
|---|---|---|---|
| TSV624IST | Same die, MiniSO10 package (3.0 × 4.9 mm); no shutdown pins; 10-pin vs 16-pin footprint. | Suitable for space-constrained PCBs where shutdown control is unnecessary and quad functionality is required without power gating. | Select when board area is critical and all four amplifiers operate continuously; avoids TSSOP16 routing complexity. |
| MCP6004-E/SL | 480 kHz GBP, 100 µA IQ per amp, 3 mV max Vio, no EMI hardening, SOIC-14 package. | Better bandwidth but 3.4× higher supply current; less suitable for multi-year battery life or RF-noisy environments. | Choose for cost-sensitive industrial controls where EMI immunity and ultra-low power are secondary to speed and availability. |
Compared with TSV624IST, the TSV624IPT offers shutdown control and larger layout tolerance but occupies more board area; versus MCP6004-E/SL, it trades 60 kHz bandwidth for 71% lower quiescent current and proven 92 dB EMI rejection - decisive for medical wearables and long-life IoT sensors.

FAQ
What is the maximum capacitive load the TSV624IPT can drive without external compensation?
The TSV624IPT is unity-gain stable driving up to 100 pF capacitive load directly at its output, as verified in ST's datasheet Figure 6 and Section 4.6. For loads exceeding 100 pF, a series resistor (e.g., 10–100 Ω) between the op-amp output and the capacitor is recommended to maintain phase margin above 40° and prevent peaking or oscillation.
Does the TSV624IPT support true single-supply operation below 1.8 V?
Yes - the TSV624IPT is fully specified and functional from 1.5 V to 5.5 V supply. Electrical characteristics including input offset voltage, GBP, and output swing are characterized at 1.8 V, and application note Section 4.1 confirms stable operation down to 1.5 V with validated performance curves for supply current, output drive, and noise.
How does the shutdown function affect output state and leakage?
When SHDN3/4 pins are pulled low (to VCC−), amplifiers 3 and 4 enter shutdown mode with supply current reduced to 5 nA typ. Their outputs enter high-impedance state with ≤1 nA leakage (per Table 8), preventing loading of downstream circuitry while allowing independent control of two amplifier pairs in the quad package.
Is the TSV624IPT pin-compatible with other TSSOP16 quad op-amps like the LM324 or TLV2464?
No - the TSV624IPT uses a non-standard pinout optimized for dual shutdown control (pins 11 and 13), differing from industry-standard configurations. Its pin mapping (e.g., VCC+ on pin 15, VCC− on pin 16, dedicated SHDN pins) is unique to the TSV62x family and incompatible with LM324 or TLV2464 footprints; PCB layout must follow ST's Figure 1 schematic.
