Product details
Overview
TSV324IPT from STMicroelectronics is a quad rail-to-rail input/output operational amplifier optimized for low-voltage battery-powered systems. It operates from 2.5 V to 6 V, delivers 80 mA output current per channel, achieves 1.3 MHz gain bandwidth at 3 V, and supports extended common-mode input range (VDD − 0.2 V to VCC + 0.2 V) - enabling direct sensing in single-supply sensor interfaces and headphone driver stages.
For engineers reviewing the TSV324IPT datasheet, TSV324IPT pinout, TSV324IPT application, or TSV324IPT equivalent, key selection criteria include its 80 mA drive capability into 32 Ω loads, rail-to-rail I/O performance at 3 V, −40 °C to +125 °C operating temperature, and TSSOP14 packaging for space-constrained portable designs.
Technical Context
The TSV324IPT integrates four independent op-amps sharing a common supply, each featuring rail-to-rail input and output stages with extended common-mode voltage range beyond the rails by ±200 mV at 25 °C. Its architecture supports stable operation with capacitive loads up to 500 pF and maintains 53° phase margin under 100 pF load conditions.
Each amplifier delivers 80 mA sink/source current, exhibits 0.42–0.6 V/µs slew rate, and achieves 74–95 dB large-signal voltage gain across 600 Ω to 2 kΩ loads - making it suitable for driving audio transducers and active filter stages without external buffers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.5 V to 6 V - enables direct use in Li-ion (3.0–4.2 V) and dual-cell alkaline (3.0 V nominal) systems |
| Gain Bandwidth Product | 1.3 MHz at VCC = 3 V - sufficient for audio pre-amplification and anti-aliasing filters up to ~100 kHz |
| Output Current | ±80 mA - drives 32 Ω headphones directly without external buffer stage |
| Input Offset Voltage | 0.2–3 mV (typ/max at 25 °C) - supports precision DC-coupled sensor signal conditioning |
| Common-Mode Input Range | VDD − 0.2 V to VCC + 0.2 V - allows input signals to exceed supply rails, simplifying level-shifting circuits |
| Operating Temperature | −40 °C to +125 °C - qualified for automotive cabin and industrial control environments |
| Thermal Resistance | 100 °C/W (TSSOP14) - enables sustained 80 mA output in compact PCB layouts with moderate copper area |
Pinout & Package
TSV324IPT is housed in a 14-lead TSSOP package (thin shrink small outline package), 4.9 mm × 6.4 mm footprint, 0.65 mm lead pitch, with exposed thermal pad option not implemented - designed for high-density routing and reflow-compatible assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Amp A) | Accepts differential signal reference for first op-amp; requires impedance matching for noise rejection |
| 2 | Non-inverting input (Amp A) | High-impedance node for sensor or reference signal connection; supports rail-to-rail common-mode range |
| 3 | Output (Amp A) | Capable of sourcing/sinking 80 mA; stable with 500 pF capacitive load - suitable for driving cables or transducers |
| 4 | VDD (Ground) | Power return path; must be low-impedance with local 100 nF decoupling adjacent to pin |
| 5 | Non-inverting input (Amp B) | Independent input for second amplifier; identical electrical specs to Pin 2 |
| 6 | Inverting input (Amp B) | Differential input for Amp B; layout symmetry recommended when used in matched pairs |
| 7 | Output (Amp B) | Second independent output; shares same drive strength and stability profile as Pin 3 |
| 8 | VCC (Supply) | Positive supply rail; accepts 2.5–6 V; internal ESD protection rated to 2 kV HBM |
| 9 | Output (Amp C) | Third output channel; electrically isolated from others except shared supply/ground |
| 10 | Inverting input (Amp C) | Input for third amplifier; no internal cross-talk with other channels per datasheet characterization |
| 11 | Non-inverting input (Amp C) | High-Z input node; supports same Vicm extension (±200 mV beyond rails) as Pins 1 and 2 |
| 12 | Output (Amp D) | Fourth output; fully specified for 80 mA drive and rail-to-rail swing under all load conditions |
| 13 | Inverting input (Amp D) | Final differential input; layout should minimize trace length to reduce pickup in sensitive analog paths |
| 14 | Non-inverting input (Amp D) | Independent input for fourth amplifier; matches performance of Pins 2, 5, and 11 |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in single-supply 3 V systems - output swings within 100 mV of rails with 600 Ω load |
| Extended Common-Mode Input | Vicm extends 200 mV beyond VDD/VCC - eliminates need for level-shifting resistors in battery-monitoring or current-sense applications |
| High Output Drive | 80 mA per channel sustains 32 Ω headphone loads at 3 V without clipping - reduces BOM count vs. discrete buffer solutions |
| Stable with Capacitive Loads | 500 pF max stable capacitance - supports direct connection to LCD bias networks or long PCB traces without compensation |
| Wide Temperature Range | −40 °C to +125 °C operation - validated for under-hood automotive modules and industrial motor controllers |

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 drive (60 mA), narrower Vicm (to rails only), 1 MHz GBP at 3 V | Not suitable for 32 Ω headphone loads or extended-rail sensor inputs | Select when cost sensitivity outweighs drive strength and input range requirements |
| TSV854IPT | Higher GBP (10 MHz), lower noise (19 nV/√Hz), but 45 mA output and 2.7 V min supply | Preferred for wideband active filters; insufficient for 32 Ω audio drive at 3 V | Choose for precision AC-coupled signal chains where bandwidth >1 MHz is critical |
Compared with LMV324IDR, TSV324IPT provides 33% higher output current and ±200 mV Vicm extension - essential for direct battery sensing. Versus TSV854IPT, it trades bandwidth and noise for robust low-voltage drive, making it optimal for power-constrained DC and audio applications.

FAQ
What is the maximum capacitive load the TSV324IPT can drive stably?
The TSV324IPT maintains stability with up to 500 pF capacitive load per output channel without external compensation, as verified in the DS4381 datasheet Figure 14–15 gain/phase plots. This enables direct interface to LCD bias networks, long coaxial cables, or unbuffered ADC inputs without risk of oscillation.
Does the TSV324IPT support true rail-to-rail input at temperatures beyond 25 °C?
Yes - the extended common-mode input range (VDD − 0.2 V to VCC + 0.2 V) is guaranteed across the full −40 °C to +125 °C operating range per Table 2 of DS4381. At temperature extremes, the Vicm shrinks slightly to VDD to VCC but remains fully rail-to-rail compliant for most single-supply applications.
Can TSV324IPT operate from a single 2.5 V supply while driving a 32 Ω load?
Yes - the device is fully specified at VCC = 2.5 V, delivering ±80 mA output current into 32 Ω loads per the "Capable of driving a 32 Ω load resistor" feature and Figure 12–13 output current vs. voltage curves. Output swing remains within 100 mV of both rails under these conditions.
How does the TSV324IPT's input offset voltage compare to the enhanced TSV324A variant?
The TSV324IPT has a typical input offset voltage of 0.2 mV and maximum of 3 mV at 25 °C, while the TSV324AIPT variant improves this to 0.1 mV typical and 1 mV maximum. This 3× tighter offset specification makes the 'A' version preferable for precision DC-coupled applications like weigh scales or medical instrumentation amplifiers.
