Product details
Overview
TS972IYPT from STMicroelectronics is a dual rail-to-rail output operational amplifier optimized for low-noise audio pre-amplification in battery-powered systems. It delivers 4 nV/√Hz input voltage noise, 0.003% THD at 1 kHz, and 4 V/µs slew rate across a 2.7–10 V supply range, operating from –40 °C to +125 °C in automotive-grade TSSOP8 packaging.
For engineers reviewing the TS972IYPT datasheet, TS972IYPT pinout, TS972IYPT application, or TS972IYPT equivalent, this device is selected for high-fidelity portable audio front-ends, precision sensor signal conditioning with wide common-mode range (±1.35 V), and space-constrained industrial control analog interfaces requiring AEC-Q100 qualified performance.
Technical Context
The TS972IYPT integrates two independent op-amps sharing a single supply rail, each featuring fully rail-to-rail output swing (±2.4 V at ±2.5 V supply) and a common-mode input range extending to within 1.15 V of either rail. Its 12 MHz gain-bandwidth product and 60° phase margin ensure stable unity-gain operation with capacitive loads up to 100 pF.
Designed for automotive environments, it includes 2 kV HBM ESD protection, latch-up immunity per JEDEC Class A, and thermal resistance of 120 °C/W (junction-to-ambient, TSSOP8). Input bias current remains below 750 nA over temperature, enabling high-impedance transducer interfacing without significant DC error.
Key Specifications

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 |
|---|---|---|---|
| TLV2772IDR | Higher input noise (7 nV/√Hz), lower GBW (10 MHz), no AEC-Q100 qualification | Targeted at commercial portable devices, not automotive or medical grade | Select when cost sensitivity outweighs noise and qualification requirements |
| OPA2188AIDR | Zero-drift architecture (0.005 µV/°C drift), higher supply current (1 mA/ch), 2 MHz GBW | Better for DC-precision applications (e.g., weigh scales), less suitable for audio bandwidth | Choose for ultra-low offset drift where AC performance is secondary |
Compared with TLV2772IDR and OPA2188AIDR, the TS972IYPT uniquely balances low noise, audio-grade linearity, automotive qualification, and rail-to-rail output-making it optimal for mixed-signal systems demanding both fidelity and reliability.

FAQ
What is the maximum capacitive load the TS972IYPT can drive stably?
The TS972IYPT maintains 60° phase margin and unity-gain stability with up to 100 pF capacitive load when configured with RL = 2 kΩ, as verified in Figure 10 of the datasheet. For loads exceeding 100 pF, an isolation resistor (≥10 Ω) between output and capacitance is required to prevent peaking or oscillation.
Does the TS972IYPT require external compensation for unity-gain operation?
No external compensation is needed: the TS972IYPT is internally compensated for stable unity-gain operation across its full supply range (2.7–10 V) and temperature range (–40 to +125 °C), confirmed by phase margin ≥60° in Table 3 and Figure 11 of the datasheet.
How is the exposed thermal pad on the TSSOP8 package intended to be connected?
The exposed pad (Pin 4) is electrically connected to VDD and must be soldered to a PCB copper pour tied to the negative supply plane. This reduces thermal resistance by ~40 °C/W and improves long-term reliability under continuous 5 mA output current conditions.
Can the TS972IYPT operate from a single 3.3 V supply while maintaining rail-to-rail output?
Yes: with VCC = 3.3 V and VDD = 0 V, the output swings from 50 mV above ground to 3.25 V - achieving >98% of rail-to-rail range. The common-mode input range extends from 1.15 V to 2.15 V, supporting mid-supply referenced signal sources.
