Product details
Overview
TS951RIYLT from STMicroelectronics is a single-channel rail-to-rail input/output BiCMOS operational amplifier optimized for 3 V and 5 V battery-powered systems. It delivers 3 MHz gain-bandwidth, 1 V/µs slew rate, 0.9 mA supply current at 3 V, 80 dB supply voltage rejection, and operates from 2.7 V to 12 V. Its SOT23-5 package enables compact placement in portable medical instrumentation and automotive signal conditioning circuits.
For engineers reviewing the TS951RIYLT datasheet, TS951RIYLT pinout, TS951RIYLT application, or TS951RIYLT equivalent, this page provides verified technical context, validated pin functions, confirmed rail-to-rail performance metrics, automotive-grade qualification status (AEC-Q100), and real-world design implications for low-voltage precision amplification.
Technical Context
The TS951RIYLT employs a BiCMOS input stage enabling rail-to-rail common-mode input range (VDD − 0.2 V to VCC + 0.2 V) and rail-to-rail output swing (within 100 mV of rails at 600 Ω load). Its 3 MHz unity-gain bandwidth and 1 V/µs slew rate support stable operation in active filtering and DAC buffering with minimal phase margin degradation (60° at unit gain).
Designed for automotive-grade reliability, it features latch-up immunity up to 200 mA, 1.5 kV HBM ESD rating, and operates across −40 °C to +125 °C. The device maintains 80 dB CMRR and 80 dB SVR over full temperature and supply range, ensuring robust performance in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 12 V - supports direct integration into 3.3 V microcontroller I/O domains and 12 V automotive subsystems without level-shifting. |
| Gain-Bandwidth Product | 3 MHz - enables stable closed-loop gain ≥10 at 300 kHz for anti-aliasing filter design in 1 MSPS data acquisition systems. |
| Slew Rate | 1 V/µs - ensures ≤1 µs settling time for 1 V step inputs, critical for driving capacitive loads in headphone driver stages. |
| Input Offset Voltage | 6–8 mV (max) - limits DC error to <±1 LSB in 12-bit DAC buffer applications with 4.096 V reference. |
| Supply Current per Amplifier | 0.9–1.3 mA at 3 V - allows 10+ amplifiers on a 30 mA battery rail in portable diagnostic devices. |
| Output Voltage Swing | Within 100 mV of rails at 600 Ω - delivers full dynamic range to 16 Ω headphones or 1 kΩ sensor interfaces without headroom loss. |
| Common-Mode Rejection | 50–80 dB - suppresses 100 mV power-supply ripple to ≤3 mV at output, essential for precision analog front-ends. |
Pinout & Package
SOT23-5 micropackage (2.9 mm × 2.8 mm footprint, 1.2 mm height) with exposed pad option for thermal enhancement; qualified per AEC-Q100 Grade 1 (−40 °C to +125 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN−) | Inverting input | Accepts feedback network connection; rail-to-rail input range enables direct sensing of signals near ground or VCC. |
| 2 (IN+) | Non-inverting input | Supports high-impedance sensor interface (Iib = 35–200 nA); immune to latch-up under ±1 V differential stress. |
| 3 (V− / VSS) | Negative supply | Ground-referenced operation down to 0 V; supports single-supply configurations with no negative rail required. |
| 4 (OUT) | Amplifier output | Rail-to-rail swing (2.8 V high / 0.25 V low at 3 V supply, 600 Ω load); drives 100 pF capacitive loads stably. |
| 5 (V+ / VDD) | Positive supply | Accepts 2.7–12 V; 80 dB SVR minimizes supply noise coupling into audio or sensor signal paths. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Extends to VDD − 0.2 V and VCC + 0.2 V - eliminates need for input biasing resistors in single-supply transducer interfaces. |
| Rail-to-rail output swing | Delivers >97% of supply rail-to-rail span at 600 Ω - maximizes SNR in 3.3 V ADC driver applications. |
| Low quiescent current | 0.9 mA at 3 V - enables >100-hour battery life in portable ECG monitors using coin-cell power. |
| AEC-Q100 qualified | Grade 1 (−40 °C to +125 °C), PPAP-capable - meets automotive infotainment and body control module requirements without derating. |
| Latch-up immunity | 200 mA - withstands transient overcurrent events during hot-plug or ESD discharge without functional interruption. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-channel rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS951ILT | Same silicon, commercial grade (−40 °C to +85 °C), non-automotive marking (K101 vs K103) | Lacks AEC-Q100 qualification; unsuitable for under-hood or safety-critical automotive use | Select when cost-sensitive consumer designs require identical electrical specs without automotive validation. |
| MCP6001T-E/OT | Lower GBW (1 MHz), higher Vio (1.5 mV typ), same SOT23-5 package and 2.7–5.5 V range | Better DC precision but insufficient bandwidth for >500 kHz active filters or fast DAC settling | Prefer for ultra-low-power (<100 µA) sensor buffers where speed is secondary to battery longevity. |
Compared with TS951ILT, TS951RIYLT adds automotive qualification and tighter production screening; versus MCP6001T-E/OT, it trades lower quiescent current for 3× higher bandwidth and proven rail-to-rail drive capability into 600 Ω loads.

FAQ
Is TS951RIYLT pin-compatible with TS951ILT?
Yes-both share identical SOT23-5 pinout (IN−, IN+, V−, OUT, V+), same footprint, and identical electrical specifications. The only differences are automotive qualification (AEC-Q100 Grade 1), enhanced screening, and marking code (K103 vs K101), making TS951RIYLT a drop-in replacement where automotive reliability is mandated.
What is the maximum capacitive load the TS951RIYLT can drive without instability?
The TS951RIYLT remains stable driving up to 100 pF with 60° phase margin (per datasheet Figure 3), provided a 600 Ω series resistor is placed between output and load. For >100 pF loads (e.g., long PCB traces), a 47 Ω isolation resistor is recommended to maintain stability while preserving bandwidth.
Does TS951RIYLT support dual-supply operation?
Yes-it operates with split supplies (e.g., ±2.5 V to ±6 V) as well as single-ended (2.7–12 V). The common-mode input range extends 0.2 V beyond both rails, and output swings within 100 mV of each supply, enabling true bipolar signal processing without external level shifters.
How does the 80 dB supply voltage rejection ratio impact system-level noise performance?
At 80 dB SVR, a 100 mV ripple on the 3.3 V supply contributes only ~100 µV of error at the output-well below typical 12-bit ADC quantization steps (806 µV). This enables direct connection to noisy digital supply rails in mixed-signal SoC systems without dedicated LDO filtering.
