Product details
Overview
TS971IYLT from STMicroelectronics is a single-channel rail-to-rail output operational amplifier optimized for automotive-grade audio pre-amplification and low-noise signal conditioning. It delivers 4 nV/√Hz input voltage noise, 0.003% THD at 1 kHz, 12 MHz gain bandwidth, 4 V/µs slew rate, and operates from 2.7 V to 10 V supply with ±2.4 V output swing at ±2.5 V rails.
For engineers reviewing the TS971IYLT datasheet, TS971IYLT pinout, TS971IYLT application, or TS971IYLT equivalent, key selection criteria include its AEC-Q100 qualified SOT23-5 package, ultra-low distortion for audio front-ends, rail-to-rail output drive into 2 kΩ loads, and thermal performance validated up to +125 °C ambient.
Technical Context
The TS971IYLT employs a bipolar input stage with rail-to-rail output complementary push-pull stage, enabling full dynamic range utilization in single-supply or split-supply configurations. Its phase margin remains ≥60° across load currents up to 10 mA and supply voltages from 2.7 V to 10 V, ensuring stable unity-gain operation with capacitive loads up to 130 pF.
Designed for automotive environments, it features latch-up immunity (Class A), 2 kV HBM ESD protection, and guaranteed operation from −40 °C to +125 °C. Input common-mode range extends from VDD + 1.15 V to VCC − 1.15 V, supporting biasing flexibility in sensor interface and active filter topologies.

Equivalent & Alternatives
The following parts are listed as comparable options for similar rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV721QMG/NOPB | Higher input bias current (1.2 µA vs. 200 nA typ), lower GBW (10 MHz), no AEC-Q100 qualification | Not suitable for high-Z sensor nodes or automotive deployment; limited to commercial-temp consumer audio | Select only if cost sensitivity outweighs noise, drift, and qualification requirements |
| OPA333AIDBVR | Zero-drift architecture (0.02 µV/°C drift), lower noise (1.1 µVPP), but slower slew rate (0.16 V/µs) and lower GBW (350 kHz) | Optimized for DC precision, not AC fidelity-unsuitable for audio or fast transient response | Prefer for thermocouple amplification or strain gauge bridges; avoid for audio or dynamic signal paths |
Compared with LMV721QMG/NOPB and OPA333AIDBVR, TS971IYLT uniquely balances ultra-low noise, high-speed dynamics, and automotive qualification-making it the only choice when all three attributes are required simultaneously in space-constrained SOT23-5 layouts.

FAQ
Is TS971IYLT pin-compatible with TS971ILT?
Yes-both share identical SOT23-5 pinout (OUT, −IN, +IN, V−, V+), but TS971IYLT is AEC-Q100 qualified for automotive use (−40 °C to +125 °C), while TS971ILT is commercial grade (−40 °C to +85 °C). Electrical specs are identical; only qualification level differs.
Can TS971IYLT drive a 600 Ω audio load directly?
No-it is not rated for continuous 600 Ω loads. Its output sink/source capability is 1.5 mA source / 100 mA sink, limiting practical resistive loads to ≥2 kΩ. For 600 Ω lines, use external buffer stages or dedicated line drivers like TPA6130A2.
What is the maximum capacitive load TS971IYLT can drive without oscillation?
It remains stable with up to 130 pF capacitive load at unity gain (per Figure 12), provided proper PCB layout (short traces, local bypassing, ground plane). For >130 pF, add a series resistor (≥10 Ω) between output and load to isolate capacitance.
Does TS971IYLT require external compensation for unity-gain stability?
No-it is internally compensated for unity-gain stability across its full operating range (2.7 V to 10 V, −40 °C to +125 °C), as confirmed by phase margin ≥60° in Table 3 and Figure 11. No external components are needed for standard non-inverting or inverting configurations.
