Product details
Overview
TS924AIDT from STMicroelectronics is a rail-to-rail input/output quad operational amplifier optimized for 2.7 V to 12 V single-supply operation, delivering 80 mA output current per channel, 4 MHz gain-bandwidth product, and 9 nV/√Hz input voltage noise - enabling direct drive of 32 Ω headphone loads in portable audio systems.
For engineers reviewing the TS924AIDT datasheet, TS924AIDT pinout, TS924AIDT application, or TS924AIDT equivalent, this device is selected for low-noise, high-output-current, rail-to-rail analog signal conditioning in battery-powered audio, instrumentation, and multimedia interfaces where DC precision (900 µV max input offset) and capacitive load stability (up to 500 pF) are critical.
Technical Context
The TS924AIDT employs BiCMOS input stages for low input bias current (15–100 nA) and rail-to-rail input common-mode range (VCC− − 0.2 V to VCC+ + 0.2 V), paired with robust output stages capable of sourcing/sinking ±80 mA into low-impedance loads. Its 1.3 V/µs slew rate and 68° phase margin ensure stable unity-gain operation with 100 pF capacitive loads.
It achieves 0.005% THD at 1 kHz driving 600 Ω, 120 dB channel separation, and 80 dB CMRR across 0–5 V common-mode range - confirming suitability for multi-channel signal integrity-critical applications such as stereo line drivers and piezoelectric transducer excitation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 12 V single supply - supports direct integration into 3 V and 5 V battery-powered systems without level-shifting. |
| Input Offset Voltage | ≤900 µV (max, full temp range) - enables precision DC-coupled amplification in sensor front-ends and active filters. |
| Output Current | ±80 mA per channel - drives 32 Ω headphones or piezo elements without external buffers. |
| Gain-Bandwidth Product | 4 MHz - supports audio bandwidth extension beyond 20 kHz with adequate phase margin. |
| Input Voltage Noise | 9 nV/√Hz at 1 kHz - preserves SNR in low-level microphone preamp and instrumentation amplifier stages. |
| THD + Noise | 0.005% at 1 kHz, 2 Vpk-pk, RL = 600 Ω - meets high-fidelity audio requirements for sound cards and MPEG boards. |
| Capacitive Load Drive | Stable up to 500 pF - allows direct connection to long PCB traces or LCD panel drivers without isolation resistors. |
Pinout & Package
TS924AIDT is supplied in a 14-pin SOIC (SO14) package with standard quad op-amp pinout and 1.27 mm pitch. The package complies with ECOPACK® environmental specifications and supports reflow soldering up to 260 °C (lead-free).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 12 | Inverting input (A, B, C, D) | High-impedance differential inputs accepting rail-to-rail common-mode signals (VCC− − 0.2 V to VCC+ + 0.2 V). |
| 2, 6, 10, 13 | Non-inverting input (A, B, C, D) | Matched input impedance to inverting pins; enables unity-gain buffer or precision non-inverting gain configurations. |
| 3, 7, 11, 14 | Output (A, B, C, D) | Rail-to-rail output stage capable of sourcing/sinking 80 mA; specified for 32 Ω load drive at 2.7–12 V supply. |
| 4 | VCC+ | Positive supply terminal - accepts 2.7–12 V; decoupling capacitor required near pin for stability. |
| 8 | VCC− | Negative supply / ground reference - must be connected to system ground in single-supply configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in low-voltage systems (e.g., 3 V battery rails), eliminating headroom loss in DC-coupled paths. |

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 |
|---|---|---|---|
| TS924IDT | Higher input offset voltage (≤1.8 mV max) and wider offset drift (3 µV/°C vs. 2 µV/°C); otherwise identical AC specs and pinout. | Suitable for cost-sensitive audio line drivers where DC accuracy is secondary to AC performance. | Select TS924IDT if system-level calibration compensates for higher offset; prefer TS924AIDT for uncalibrated DC-coupled sensor interfaces. |
| TSX564IPT | Smaller TSSOP14 package; lower supply current (850 µA/op vs. 1.6 mA/op); reduced output current (60 mA vs. 80 mA); same 4 MHz GBW. | Better suited for space-constrained, ultra-low-power applications where 32 Ω drive is not required. | Choose TSX564IPT for wearable devices with tight board area and <1 mA total quiescent budget; retain TS924AIDT for full-load audio fidelity. |
Compared with TS924IDT, TS924AIDT provides tighter DC precision essential for uncalibrated analog front-ends; versus TSX564IPT, it trades higher quiescent current for superior output drive strength and noise performance - making it optimal for high-fidelity, low-Z audio and instrumentation where signal integrity outweighs power savings.

FAQ
What is the maximum capacitive load the TS924AIDT can drive stably?
The TS924AIDT is characterized for stable operation with capacitive loads up to 500 pF without external compensation. This specification is verified under standard test conditions (VCC = 3 V, RL = 600 Ω, CL = 100 pF) and confirmed via phase margin measurements (68°) and transient response testing. Loads exceeding 500 pF may require series output resistance or feedback network adjustment.
Does TS924AIDT support true rail-to-rail input common-mode range?
Yes - the TS924AIDT accepts input voltages from VCC− − 0.2 V to VCC+ + 0.2 V, enabling full-rail operation in single-supply configurations. This is achieved via complementary BiCMOS input pairs and is validated across the full temperature range (−40 °C to +125 °C) and supply range (2.7 V to 12 V).
Can TS924AIDT be used in dual-supply configurations?
Yes - the device operates with split supplies (e.g., ±1.5 V to ±6 V) as confirmed in the datasheet's electrical characteristics tables. Pin 4 is VCC+ and Pin 8 is VCC−; common-mode and output swing remain rail-to-rail relative to the applied supply rails, supporting bipolar signal processing in instrumentation and test equipment.
What is the thermal resistance (RthJA) of the SO14 package?
The SO14 package has a typical junction-to-ambient thermal resistance (RthJA) of 66 °C/W under standard JEDEC 2-layer board conditions. This value assumes 1 in² copper pad with 2 oz copper and is used to calculate maximum allowable power dissipation (PD = (TJMAX − TA) / RthJA) for ambient temperatures up to +85 °C.
