Product details
Overview
TSV324IYDT 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 supply rail (at 600 Ω load), features 1.3 MHz gain bandwidth at 3 V, and is rated for -40 °C to +125 °C operation in SO14 package.
For engineers reviewing the TSV324IYDT datasheet, TSV324IYDT pinout, TSV324IYDT application, or TSV324IYDT equivalent, key selection criteria include its extended common-mode input range (VDD − 0.2 V to VCC + 0.2 V), capability to drive 32 Ω loads, 500 pF capacitive stability, low 650 µA per-amplifier supply current, and automotive-grade qualification per AEC-Q100.
Technical Context
The TSV324IYDT integrates four independent op-amps on a single die with fully rail-to-rail input and output stages, enabling signal conditioning across the full supply range in battery-powered systems. Its input stage extends 200 mV beyond both rails at 25 °C, while output swing remains within 100 mV of VDD/VCC under 600 Ω load - critical for low-voltage audio and sensor interfaces.
Designed as a low-voltage upgrade to LM324, it maintains compatibility while improving performance: 1.3 MHz GBP at 3 V, 0.6 V/µs slew rate, 80 dB CMRR, and 90 dB SVRR ensure precision in active filters, portable instrumentation, and multi-channel analog front-ends where power efficiency and dynamic range are constrained.
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 min) systems. |
| Gain Bandwidth Product | 1.3 MHz at VCC = 3 V - supports stable unity-gain buffers and 2nd-order active filters up to ~100 kHz. |
| Output Current | ±80 mA typical - drives 32 Ω headphone loads or 600 Ω transducer interfaces without external buffers. |
| Input Offset Voltage | 3 mV max (TSV324), 1 mV max (TSV324A) - ensures <100 µV error in 3.3 V sensor amplifiers with 100× gain. |
| Common-Mode Input Range | VDD − 0.2 V to VCC + 0.2 V at 25 °C - accepts inputs beyond supply rails, simplifying level-shifting in mixed-supply designs. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive, industrial motor control, and ruggedized portable equipment. |
| Supply Current per Amp | 650 µA typ. at 3 V - enables four-channel signal conditioning with <2.6 mA total quiescent draw. |
Pinout & Package
TSV324IYDT is housed in a 14-pin SOIC (SO14) package with standard 1.27 mm pitch, 8.55–8.75 mm body width, and 5.8–6.2 mm body length. Thermal resistance junction-to-ambient is 105 °C/W, supporting continuous operation at full output current in ambient up to 85 °C with minimal heatsinking.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (AMP A) | Accepts differential signal referenced to non-inverting input; supports rail-to-rail common-mode range. |
| 2 | Non-inverting input (AMP A) | High-impedance node (125 nA bias current); compatible with high-Z sensors and resistive dividers. |
| 3 | Output (AMP A) | Delivers ±80 mA into resistive loads; stable with 500 pF capacitive load - suitable for driving cables or ADC inputs. |
| 4 | VDD (Ground) | Low-side reference for all amplifiers; must be connected to system ground plane for noise immunity. |
| 5 | Non-inverting input (AMP B) | Independent channel input; identical electrical specs to Pin 2 - enables parallel sensor channels. |
| 6 | Inverting input (AMP B) | Matches Pin 1 functionality; supports differential configurations or inverting gain stages. |
| 7 | Output (AMP B) | Full rail-to-rail swing; can source/sink 80 mA - used for dual-channel audio or redundant signal paths. |
| 8 | VCC (Supply) | Positive supply rail (2.5–6 V); decoupling capacitor (100 nF) required within 5 mm for stability. |
| 9 | Output (AMP C) | Third independent output; enables 3-channel signal processing (e.g., stereo + subwoofer or tri-axis sensor). |
| 10 | Inverting input (AMP C) | Matches Pins 1 and 6; supports cascaded filtering or summing configurations without cross-talk. |
| 11 | Non-inverting input (AMP C) | High-CMRR input; rejects supply noise when biased mid-rail via resistor divider. |
| 12 | Non-inverting input (AMP D) | Fourth channel input; allows simultaneous conditioning of four analog signals (e.g., quad thermistor array). |
| 13 | Inverting input (AMP D) | Configurable for unity-gain buffer or inverting amplifier; same offset and drift specs as other inputs. |
| 14 | Output (AMP D) | Final output channel; capable of 32 Ω load drive - used for local feedback or direct transducer excitation. |

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 | Wider supply range (2.7–5.5 V), lower GBP (1 MHz), higher input bias current (250 nA), no AEC-Q100 qualification. | Targeted at cost-sensitive consumer electronics; lacks extended Vicm and automotive reliability. | Select when budget constraints outweigh thermal/automotive requirements and 3.3 V operation suffices. |
| TSV854IPT | Higher GBP (12 MHz), lower noise (17 nV/√Hz), higher supply current (1.3 mA/amp), TSSOP14 package only. | Optimized for high-speed active filters and precision instrumentation; not drop-in due to different pinout and quiescent power. | Choose for bandwidth-critical designs requiring >5× GBP improvement, accepting higher power and re-layout effort. |
Compared with LMV324IDR, TSV324IYDT offers superior rail-to-rail input range, automotive qualification, and lower input offset - making it preferable for harsh-environment sensing. Against TSV854IPT, it trades bandwidth and noise performance for 50% lower supply current and broader voltage flexibility, favoring battery life over speed.

FAQ
What is the maximum capacitive load the TSV324IYDT can drive stably?
The TSV324IYDT is characterized for stable operation with up to 500 pF capacitive load, maintaining ≥53° phase margin per amplifier. This enables direct driving of ADC input capacitors, long PCB traces, or small-signal cables without external isolation resistors. For loads exceeding 500 pF, a series resistor (≥10 Ω) between output and capacitance is recommended to preserve stability.
Does TSV324IYDT support single-supply operation below 3 V?
Yes - TSV324IYDT operates down to 2.5 V supply, with verified rail-to-rail input/output performance and 1.3 MHz GBP at 3 V. At 2.5 V, GBP reduces to ~1.1 MHz and output current remains ≥70 mA, making it suitable for coin-cell-powered devices and ultra-low-power IoT sensors where 3 V regulation is impractical.
How does the TSV324IYDT differ from the TSV324A variants?
The TSV324IYDT uses the standard TSV324 grade (max 3 mV input offset voltage), while TSV324AIYDT specifies tighter offset (1 mV max) and enhanced ESD robustness (4 kV HBM). Both share identical pinout, package, temperature range, and AC specs - the A-grade is selected when offset-critical applications like precision thermistor bridges or low-gain strain gauge amplifiers demand sub-millivolt error budgets.
Can TSV324IYDT be used in inverting amplifier configurations with gain >100?
Yes - with GBP of 1.3 MHz at 3 V, TSV324IYDT supports stable inverting amplifiers up to gain × bandwidth ≤ 1.3 MHz (e.g., gain 100 usable to 13 kHz). Stability is ensured by its 53° phase margin and 500 pF capacitive drive capability; for gains >100, use 100 pF compensation capacitor across feedback resistor if high-frequency ringing occurs.
