Product details
Overview
TSV324IYPT from STMicroelectronics is a quad rail-to-rail input/output operational amplifier optimized for low-voltage, high-output-drive applications. It operates from 2.5 V to 6 V, delivers ±80 mA output current, supports rail-to-rail I/O swing within 100 mV of each rail (600 Ω load), features 1.3 MHz gain bandwidth at 3 V, and is rated for -40 °C to +125 °C operation - ideal for battery-powered sensor signal conditioning and headphone driver circuits in portable industrial and automotive systems.
For engineers reviewing the TSV324IYPT datasheet, TSV324IYPT pinout, TSV324IYPT application, or TSV324IYPT equivalent, key selection criteria include its extended common-mode input range (VDD − 0.2 V to VCC + 0.2 V), 500 pF capacitive load stability, 0.6 V/µs slew rate, low 420–650 µA supply current per amplifier, and SO14/TSSOP14 package compatibility with space-constrained PCB layouts.
Technical Context
The TSV324IYPT implements a CMOS input stage enabling rail-to-rail input common-mode voltage extension beyond supply rails by ±200 mV at 25 °C, paired with a robust AB-class output stage capable of sourcing/sinking up to 80 mA. Its internal compensation ensures stable operation with ≥500 pF capacitive loads without external compensation.
It achieves 1.3 MHz gain bandwidth product at VCC = 3 V and RL = 10 kΩ, with 0.42–0.6 V/µs slew rate and 53–55° phase margin - supporting precision DC-coupled amplification and moderate-frequency AC signal conditioning (e.g., audio band up to ~100 kHz) while maintaining low THD (0.01%) and 27 nV/√Hz input voltage noise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.5 V to 6 V - enables direct use with single-cell Li-ion (3.0–3.7 V) or dual-cell alkaline (3.0 V) power rails. |
| Gain Bandwidth Product | 1.3 MHz at 3 V - supports unity-gain stable operation up to ~100 kHz with adequate phase margin for sensor filters. |
| Output Current | ±80 mA - drives 32 Ω headphone loads or 600 Ω instrumentation lines without external buffers. |
| Input Offset Voltage | 0.2–3 mV (typ/max, 25 °C) - ensures <1 mV error in 1×–10× gain sensor front-ends at room temperature. |
| Common-Mode Input Range | VDD − 0.2 V to VCC + 0.2 V - accepts signals beyond supply rails, simplifying level-shifting in mixed-supply systems. |
| Slew Rate | 0.42–0.6 V/µs - limits full-power bandwidth to ~100 kHz but preserves fidelity for audio and slow-control loops. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive and industrial edge-sensor environments. |
Pinout & Package
TSV324IYPT is available in SO14 (small outline 14-pin) and TSSOP14 (thin shrink small outline 14-pin) packages. Both are surface-mount, lead-free ECOPACK®-compliant packages with 1.27 mm pitch; SO14 offers higher thermal dissipation (RthJA = 105 °C/W), while TSSOP14 provides 30% smaller footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 12 | Inverting Input (−) | Differential input node for each of four op-amps; accepts rail-to-rail common-mode voltage. |
| 2, 6, 10, 13 | Non-inverting Input (+) | Differential input node; matched bias current minimizes offset in high-Z sensor interfaces. |
| 3, 7, 11, 14 | Output | Class-AB rail-to-rail output capable of ±80 mA drive into resistive or capacitive loads. |
| 4 | VDD (Ground) | Reference ground terminal for all four amplifiers; requires low-impedance local decoupling. |
| 8 | VCC (Supply) | Positive supply input (2.5–6 V); connects to bulk and local ceramic decoupling (100 nF + 1 µF). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input extends 200 mV beyond supplies; output swings to within 100 mV of rails (600 Ω load), maximizing dynamic range in low-voltage systems. |
| High Output Drive | ±80 mA per amplifier enables direct driving of 32 Ω headphones or 600 Ω analog outputs without external transistors. |
| Capacitive Load Stability | Stable with ≥500 pF load - eliminates need for isolation resistors when driving ADC inputs or long traces. |
| Low Power Operation | 650 µA max supply current per amplifier at 25 °C - extends battery life in always-on sensor nodes. |
| Extended Temp Range | Specified from −40 °C to +125 °C - supports deployment in automotive cabin modules and industrial motor controllers. |
Applications
| Audio Signal Amplification | Sensor Front-End Conditioning |
|---|---|
|
Use Scenario: Driving stereo headphone outputs in portable medical monitors or handheld test equipment. IC Role / Device Role / Timing Role: Quad op-amp configured as two independent stereo line drivers (each channel using one amplifier pair), leveraging rail-to-rail output to maximize loudness at 3.3 V supply. Use Value: Eliminates need for discrete output buffers or charge-pump rails, reducing BOM count and PCB area while delivering >100 mW into 32 Ω. |
Use Scenario: Amplifying low-level bridge sensor outputs (e.g., pressure or strain gauges) in automotive tire pressure monitoring systems (TPMS). IC Role / Device Role / Timing Role: Instrumentation amplifier front-end (using two op-amps in difference configuration) with rail-to-rail input accepting near-ground common-mode voltages. Use Value: Enables direct interface to millivolt-level sensors without level-shifting circuitry, improving SNR and reducing offset drift over temperature. |
| Laptop Battery Monitoring | Industrial Analog I/O Module |
|
Use Scenario: Measuring cell voltage and current in multi-cell Li-ion battery packs inside ultrabooks. IC Role / Device Role / Timing Role: Quad amplifier used for simultaneous voltage sensing (2 channels), current shunt amplification (1 channel), and reference buffering (1 channel). Use Value: Single SO14 package replaces four discrete SOT23-5 op-amps, cutting assembly cost and layout complexity while maintaining 0.2 mV input offset accuracy. |
Use Scenario: Signal conditioning for 4–20 mA loop receivers and thermocouple inputs in DIN-rail mounted PLC analog input cards. IC Role / Device Role / Timing Role: Precision buffer and gain stage operating from isolated 5 V rails, exploiting extended Vicm to handle negative common-mode transients during field wiring faults. Use Value: Withstands −0.2 V to +5.2 V input range at 5 V supply, preventing latch-up during ESD or surge events on field-connected terminals. |
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 |
|---|---|---|---|
| LMV324IDR | Lower GBP (1 MHz), higher input bias current (150 nA vs. 125 nA typ), same SO14 package. | Less suitable for high-Z pH or photodiode sensors due to higher bias current; acceptable for general-purpose buffering. | Select when cost sensitivity outweighs need for extended Vicm or 1.3 MHz bandwidth. |
| TSV854IPT | Higher GBP (12 MHz), lower noise (19 nV/√Hz), wider supply (2.7–16 V), TSSOP14 only. | Better for active filter design or wideband sensor interfaces; overkill for DC-coupled battery monitoring. | Choose when bandwidth >5 MHz or sub-20 nV/√Hz noise is required - at higher unit cost and power (1.1 mA/amplifier). |
Compared with LMV324IDR, TSV324IYPT offers superior input voltage range and bandwidth for low-voltage precision; versus TSV854IPT, it trades bandwidth and noise performance for lower quiescent current and broader supply flexibility down to 2.5 V.

FAQ
What is the maximum capacitive load the TSV324IYPT can drive without oscillation?
The TSV324IYPT is specified stable with ≥500 pF capacitive loads under all operating conditions, per DS4381 Rev 9 Section 2. This stability holds without external compensation or isolation resistors, making it suitable for driving ADC inputs, long cables, or piezoelectric sensor interfaces directly.
Does TSV324IYPT support true rail-to-rail input when powered from 2.5 V?
Yes - at VCC = 2.5 V and Tamb = 25 °C, the common-mode input range is specified as VDD − 0.2 V to VCC + 0.2 V, i.e., −0.2 V to +2.7 V. This allows input signals to extend 200 mV beyond both supply rails, critical for interfacing with grounded sensors or bipolar signal sources.
How does the output current capability change across temperature?
Output current remains stable at ±80 mA (min) from −40 °C to +125 °C, as confirmed in Figure 11 (DS4381 Rev 9, page 7). The device maintains this drive strength even at maximum junction temperature, enabling reliable headphone or actuator control in thermally demanding enclosures.
Is TSV324IYPT pin-compatible with standard LM324 SO14 footprints?
Yes - TSV324IYPT uses the industry-standard SO14 pinout (pin 1 = Amp1−, pin 2 = Amp1+, pin 3 = Amp1 out, ..., pin 8 = VCC, pin 4 = VDD), matching LM324, LMV324, and TLV2464. No PCB redesign is needed when upgrading from legacy quad op-amps to this rail-to-rail solution.
