Product details
Overview
TS972IYDT from STMicroelectronics is a dual-channel, rail-to-rail output, very low-noise operational amplifier optimized for automotive-grade signal conditioning in battery-powered audio and sensing systems. It delivers 4 nV/√Hz input voltage noise, 0.003% THD at 1 kHz, 12 MHz gain-bandwidth product, and operates from ±1.35 V to ±5 V supply (2.7–10 V single-supply), with guaranteed performance from –40 °C to +125 °C.
For engineers reviewing the TS972IYDT datasheet, TS972IYDT pinout, TS972IYDT application, or TS972IYDT equivalent, this device is selected for high-fidelity pre-amplification, precision sensor buffering, and low-distortion analog front-ends where AEC-Q100 qualification, rail-to-rail swing, and sub-5 nV/√Hz noise are mandatory design requirements.
Technical Context
The TS972IYDT implements a bipolar-input, fully differential op-amp architecture with internal compensation for unity-gain stability across its full operating range. Its rail-to-rail output stage uses complementary emitter-follower drivers to achieve ±2.4 V swing into 2 kΩ at ±2.5 V supplies, while maintaining phase margin ≥60° and gain margin ≥10 dB under typical load conditions.
It features ultra-low distortion (0.003% THD) and high slew rate (4 V/µs) enabled by optimized transconductance and output stage biasing - critical for wideband audio and fast transient response in automotive sensor interfaces. Input offset voltage drift is specified at 5 µV/°C, supporting stable DC-coupled operation over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Noise | 4 nV/√Hz at 100 kHz - enables high-SNR audio pre-amplification without audible hiss |
| THD + N | 0.003 % at 1 kHz, RL = 10 kΩ - preserves harmonic integrity in professional audio paths |
| Gain Bandwidth Product | 12 MHz - supports stable closed-loop gain up to 10× at 1 MHz for anti-alias filtering |
| Slew Rate | 4 V/µs - ensures <100 ns rise time for 1 V step, minimizing transient distortion |
| Supply Range | 2.7 V to 10 V single-supply or ±1.35 V to ±5 V dual-supply - compatible with 3.3 V and 5 V automotive domains |
| Operating Temperature | –40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and infotainment use |
| Output Swing | ±2.4 V at ±2.5 V supply - delivers >96% of rail-to-rail dynamic range for maximum ADC utilization |
Pinout & Package
TS972IYDT is housed in an SO8 package (8-pin small outline integrated circuit) with exposed pad for thermal enhancement. The package meets ECOPACK® environmental compliance standards and supports surface-mount reflow assembly.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel A) | Differential input node for first op-amp; referenced to common-mode voltage range (VDD + 1.15 V to VCC – 1.15 V) |
| 2 | Non-inverting Input (Channel A) | Positive input terminal for Channel A; accepts signals within rail-referenced common-mode range |
| 3 | Output (Channel A) | Rail-to-rail output capable of sourcing 1.5 mA and sinking 100 mA; drives 2 kΩ loads to ±2.4 V |
| 4 | VDD (Negative Supply) | Negative power rail connection; supports dual-supply operation down to –1.35 V |
| 5 | Non-inverting Input (Channel B) | Positive input for second op-amp; electrically isolated from Channel A except via shared supply rails |
| 6 | Inverting Input (Channel B) | Negative input for Channel B; matched input bias current (200–1000 nA) minimizes offset error in differential pairs |
| 7 | Output (Channel B) | Second rail-to-rail output; identical AC/DC specs to Channel A for matched dual-path designs |
| 8 | VCC (Positive Supply) | Positive power rail; supports up to 10 V single-supply or +5 V dual-supply configurations |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers ±2.4 V output at ±2.5 V supply - maximizes dynamic range for 12-bit+ ADC interfacing |
| Ultra-low THD | 0.003 % at 1 kHz - eliminates audible harmonic artifacts in microphone and line-level preamps |
| Low input voltage noise | 4 nV/√Hz - preserves SNR in high-gain sensor amplifiers (e.g., piezoelectric or MEMS microphones) |
| AEC-Q100 qualified | Grade 1 (–40 °C to +125 °C) - certified for automotive infotainment, ADAS sensor signal chains, and body control modules |
| ESD protection | 2 kV HBM - withstands handling and board-level ESD events without latch-up or parameter shift |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-noise op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS972IDT | Same silicon, industrial-grade (–40 °C to +125 °C), non-AEC-Q100 qualified | Lacks automotive qualification testing and screening; unsuitable for safety-critical vehicle systems | Select when cost-sensitive industrial or consumer designs require identical electrical specs without automotive certification |
| LMV793MA/NOPB | Lower noise (5.8 nV/√Hz), lower GBW (8.5 MHz), no AEC-Q100 rating, SO8 package | Higher distortion (0.01%) and narrower bandwidth limit use in high-fidelity audio or fast-sensing applications | Consider only for non-automotive, low-bandwidth sensor interfaces where absolute lowest cost outweighs noise and speed requirements |
Compared with TS972IDT and LMV793MA/NOPB, TS972IYDT uniquely combines AEC-Q100 Grade 1 qualification, 4 nV/√Hz noise, and 12 MHz bandwidth - making it the only choice for automotive audio front-ends requiring both reliability and high-fidelity analog performance.

FAQ
Is TS972IYDT pin-compatible with TS972IDT?
Yes - TS972IYDT and TS972IDT share identical SO8 pinout, electrical specifications, and footprint. The only difference is automotive qualification: TS972IYDT undergoes AEC-Q100 stress testing and advanced screening per Q001/Q002, while TS972IDT is rated for industrial temperature range without automotive validation.
What is the maximum capacitive load the TS972IYDT can drive stably?
TS972IYDT maintains ≥60° phase margin with up to 100 pF capacitive load when driving a 2 kΩ resistive load, as verified in Figure 10 and Table 3 of the datasheet. For loads exceeding 100 pF, external isolation resistor (≥10 Ω) is recommended to prevent peaking or oscillation.
Does TS972IYDT support single-supply operation below 3 V?
Yes - TS972IYDT operates down to 2.7 V single-supply (or ±1.35 V dual-supply). At 2.7 V, it retains rail-to-rail output swing (±1.2 V typical), 12 MHz GBW, and 4 nV/√Hz noise, enabling use in ultra-low-voltage portable and energy-harvesting systems.
How does the exposed pad on the SO8 package affect thermal performance?
The SO8 package used for TS972IYDT does not include an exposed pad - that feature applies only to DFN8 variants (e.g., TS972IYQT). The standard SO8 (TS972IYDT) has RthJA = 125 °C/W and RthJC = 40 °C/W, requiring adequate copper pour and airflow for continuous 2.8 mA per amplifier operation at +125 °C ambient.
