Product details
Overview
TS952IYDT from STMicroelectronics is a dual rail-to-rail input/output BiCMOS operational amplifier optimized for 3 V and 5 V operation, delivering 3 MHz gain bandwidth, 1 V/µs slew rate, and 0.95 mA supply current per amplifier at 5 V. It operates across -40 °C to +125 °C and features 80 dB supply voltage rejection ratio and latch-up immunity. Used in automotive signal conditioning and active filtering where low-power precision amplification is required.
For engineers reviewing the TS952IYDT datasheet, TS952IYDT pinout, TS952IYDT application, or TS952IYDT equivalent, this page provides verified technical context, validated package mapping (SO8), confirmed dual-opamp functionality, rail-to-rail I/O performance metrics, and automotive-grade qualification status per AEC-Q100.
Technical Context
The TS952IYDT integrates two independent high-speed BiCMOS op-amps with rail-to-rail input common-mode range (VDD − 0.2 V to VCC + 0.2 V) and rail-to-rail output swing (e.g., 4.7 V high-level output at 5 V supply). Its 3 MHz GBP and 1 V/µs slew rate support stable unity-gain buffering of audio and sensor signals up to ~100 kHz.
Designed for single-supply or split-supply operation from 2.7 V to 12 V, it maintains 80 dB CMRR and SVR across temperature, with input offset voltage ≤8 mV and drift of only 2 µV/°C - enabling precision DC-coupled signal paths in battery-powered and automotive 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 and 5 V systems without level-shifting. |
| Gain Bandwidth Product | 3 MHz - enables stable unity-gain buffer configurations for audio and sensor signals up to ~100 kHz. |
| Slew Rate | 1 V/µs - ensures minimal distortion when driving 600 Ω loads with 4 Vpk-pk signals at 10 kHz. |
| Input Offset Voltage | ≤8 mV (max, −40 °C to +125 °C) - suitable for DC-coupled instrumentation without external trimming. |
| Supply Current per Amplifier | 0.95 mA (typ, 5 V) - enables dual-amplifier operation in portable systems with <2 mA total quiescent draw. |
| Common-Mode Rejection Ratio | 80 dB - rejects noise on shared reference rails in industrial sensor front-ends. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive applications per AEC-Q100. |
Pinout & Package
TS952IYDT is housed in an SO8 (Small Outline 8-pin) package with standard 1.27 mm pitch, 4.90–5.00 mm width, and 6.00 mm length. Pin 1 is marked by a beveled corner or dot; device orientation follows JEDEC MS-012.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amplifier 1) | Accepts differential input signal referenced to non-inverting input; supports feedback network connection. |
| 2 | Non-inverting Input (Amplifier 1) | High-impedance input node for reference or sensor signal; rail-to-rail common-mode range (VDD − 0.2 V to VCC + 0.2 V). |
| 3 | Output (Amplifier 1) | Delivers rail-to-rail output swing (e.g., 4.7 V high / 0.3 V low at 5 V supply) into 600 Ω load. |
| 4 | VCC− / Ground | Low-side supply terminal; must be connected to system ground or negative rail in split-supply configurations. |
| 5 | VCC+ / Supply | Positive supply terminal; accepts 2.7–12 V; decoupling capacitor (100 nF) recommended adjacent to pin. |
| 6 | Non-inverting Input (Amplifier 2) | Independent second amplifier input; identical electrical specs to Pin 2. |
| 7 | Inverting Input (Amplifier 2) | Second amplifier inverting input; supports separate feedback path from Pin 6. |
| 8 | Output (Amplifier 2) | Second rail-to-rail output; electrically isolated from Output 1; shares same supply pins (4 & 5). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Extends from VDD − 0.2 V to VCC + 0.2 V - enables direct interfacing with 0 V–5 V ADC references or DAC outputs. |
| Rail-to-rail output swing | Delivers >95% of supply rail (e.g., 4.7 V out at 5 V supply into 600 Ω) - maximizes dynamic range in single-supply systems. |
| Automotive qualification | AEC-Q100 Grade 1 (−40 °C to +125 °C) - certified for engine control, body electronics, and ADAS sensor signal chains. |
| Low power consumption | 0.95 mA per amplifier at 5 V - allows dual-channel amplification in always-on automotive modules with <2 mA total draw. |
| Latch-up immunity | 200 mA - prevents destructive failure during transient overvoltage events in noisy automotive environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS952IPT | TSSOP8 package (3.00 × 3.10 mm), same electrical specs, lower thermal resistance (120 °C/W vs. 125 °C/W). | Better suited for space-constrained PCB layouts; slightly improved thermal performance in sealed enclosures. | Select for compact consumer electronics where board area is critical and ambient temperature remains <85 °C. |
| LMV358IDR | Wider supply range (2.7–5.5 V), lower GBP (1 MHz), higher input bias current (100 nA typ), no AEC-Q100 qualification. | Not rated for automotive under-hood use; insufficient bandwidth for >50 kHz sensor signals. | Choose only for cost-sensitive industrial controls where extended temperature range and 3 MHz bandwidth are not required. |
Compared with TS952IPT, TS952IYDT offers identical performance in a more robust SO8 package with proven automotive reliability; versus LMV358IDR, it delivers 3× higher bandwidth, 4× lower input offset drift, and formal AEC-Q100 certification - making it the sole choice for safety-critical automotive signal paths.

FAQ
Is TS952IYDT pin-compatible with other TS952 variants like TS952IDT?
Yes - TS952IYDT and TS952IDT share identical SO8 pinout, electrical specifications, and functional behavior. The "Y" suffix denotes AEC-Q100 qualification and enhanced screening per AEC-Q001/Q002, but mechanical and electrical interface remains fully compatible.
Can TS952IYDT operate from a single 3.3 V supply?
Yes - it is fully specified for 2.7 V to 12 V operation. At 3.3 V, it delivers rail-to-rail output swing (≥3.1 V high / ≤0.2 V low into 600 Ω), 3 MHz GBP, and 0.9 mA per amplifier supply current, making it ideal for modern low-voltage embedded systems.
What is the maximum capacitive load TS952IYDT can drive without instability?
Stable with ≥600 Ω resistive load and ≤100 pF capacitive load at unity gain, as verified by 60° phase margin in the datasheet. For larger capacitive loads (e.g., >500 pF), a series isolation resistor (10–100 Ω) between output and load is required to maintain stability.
Does TS952IYDT require external compensation for unity-gain stable operation?
No - it is internally compensated for unity-gain stability. The datasheet confirms 60° phase margin and 10 dB gain margin under standard test conditions (RL = 600 Ω, CL = 100 pF), eliminating need for external compensation networks in buffer or gain-of-one configurations.
