Product details
Overview
TS952IYD from STMicroelectronics is a dual rail-to-rail input/output BiCMOS operational amplifier optimized for 3 V and 5 V supply operation, delivering 3 MHz gain bandwidth, 1 V/µs slew rate, and 0.9 mA per amplifier supply current at 3 V. It operates across -40 °C to +125 °C and supports industrial signal conditioning and portable audio buffering in SO8 package.
For engineers reviewing the TS952IYD datasheet, TS952IYD pinout, TS952IYD application, or TS952IYD equivalent, key selection criteria include rail-to-rail I/O swing, low-voltage operation down to 2.7 V, latch-up immunity, ESD robustness (2 kV HBM), and SO8 thermal resistance (125 °C/W).
Technical Context
The TS952IYD implements 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 unity-gain stable architecture achieves 60° phase margin with 100 pF capacitive load.
It features 80 dB supply voltage rejection ratio (SVR) and 80 dB common-mode rejection ratio (CMRR) at 25 °C, with input offset voltage ≤8 mV over full temperature range and 2 µV/°C drift. The device draws only 0.95 mA per amplifier at 5 V with no load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 12 V - enables direct use with single-cell Li-ion (3.0–3.7 V), USB 5 V, and industrial 12 V rails |
| Gain Bandwidth Product | 3 MHz - supports closed-loop gain ≥10 at 300 kHz for active filter and sensor interface designs |
| Slew Rate | 1 V/µs - ensures <1% THD at 10 kHz for 4 Vpk-pk output into 10 kΩ load |
| Input Offset Voltage | ≤8 mV (max, −40 to +125 °C) - limits DC error to <0.8% of full-scale in 1 V reference buffer applications |
| Supply Current per Amp | 0.95 mA (typ, 5 V) - allows dual-amp operation under 2 mA total, critical for battery-powered instrumentation |
| Output Short-Circuit Current | ±10 mA - drives 600 Ω headphone loads or 10 kΩ DAC output buffers without external gain-stage protection |
| ESD Robustness (HBM) | 2 kV - exceeds IEC 61000-4-2 Level 2 for industrial board-level handling and assembly |
Pinout & Package
TS952IYD is housed in an SO8 (Small Outline 8-pin) package with 1.27 mm pitch, 4.90 × 6.00 mm body, and 125 °C/W junction-to-ambient thermal resistance. Pin 1 is marked by a beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Amplifier 1) | Accepts feedback network connection; referenced to VCC/2 for AC-coupled single-supply operation |
| 2 | Non-inverting input (Amplifier 1) | Connects to sensor output or DAC reference; rail-to-rail CMVR allows direct tie to ground or VCC |
| 3 | Output (Amplifier 1) | Delivers rail-to-rail swing (2.8 V high / 0.25 V low @ 3 V, 600 Ω); capable of ±10 mA sink/source |
| 4 | VCC− / Ground | Power return node; must be low-impedance path to minimize PSRR degradation and oscillation risk |
| 5 | VCC+ | Positive supply pin (2.7–12 V); decoupling capacitor (100 nF X7R) required within 5 mm of this pin |
| 6 | Non-inverting input (Amplifier 2) | Independent input for second channel; shares same VCC and ground with Amp 1 |
| 7 | Inverting input (Amplifier 2) | Second amplifier feedback node; electrically isolated from Amp 1 inputs but shares supply pins |
| 8 | Output (Amplifier 2) | Second rail-to-rail output; matched AC performance to Amp 1 (same GBP, SR, THD) |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Extends from VDD − 0.2 V to VCC + 0.2 V, enabling direct interfacing with 0 V-referenced sensors or 3.3 V logic without level-shifting |
| Rail-to-rail output swing | Drives within 100 mV of both supply rails at 600 Ω, maximizing dynamic range in 3 V audio and 5 V data-acquisition systems |
| Latch-up immunity | Rated for 200 mA injection per pin, preventing destructive failure during power sequencing or transient overvoltage events |
| Low quiescent current | 0.95 mA per amplifier at 5 V allows dual-opamp integration in always-on nodes with <2 mA total system overhead |
| High-speed, low-noise operation | 3 MHz GBP + 1 V/µs SR + 25 nV/√Hz input noise supports precision active filtering up to 300 kHz with minimal phase distortion |
Applications
| Industrial Signal Conditioning | Portable Audio Buffering |
|---|---|
|
Use Scenario: Amplifying low-level thermocouple or strain gauge outputs in PLC analog input modules. IC Role / Device Role / Timing Role: Dual-channel precision buffer and gain stage with matched DC specs across channels for differential measurement. Use Value: 8 mV max input offset and 2 µV/°C drift ensure <±1 LSB error in 12-bit systems over −40 to +85 °C ambient. |
Use Scenario: Driving 16 Ω or 32 Ω headphones from a 3.3 V DAC in handheld medical monitors. IC Role / Device Role / Timing Role: Single-supply headphone amplifier with rail-to-rail output swing and low THD (0.01 %). Use Value: 1 V/µs slew rate and 3 MHz GBP deliver clean 20 kHz audio response; 0.95 mA per amp extends battery life in coin-cell powered devices. |

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 (3.0 × 6.4 mm), 120 °C/W RthJA, same electrical specs | Better PCB area efficiency for space-constrained portable designs; lower thermal mass for faster transient response | Select when board real estate is constrained and thermal dissipation <150 mW is expected |
| LMV358IDR | Lower GBP (1 MHz), higher ICC (160 µA per amp), no latch-up immunity rating | Not suitable for high-speed or high-reliability industrial environments; lacks AEC-Q100 qualification | Choose only for cost-sensitive consumer applications where 3 MHz bandwidth and 200 mA latch-up immunity are not required |
Compared with TS952IPT, TS952IYD offers superior thermal management in high-ambient environments due to SO8's lower RthJA; versus LMV358IDR, it delivers 3× bandwidth, 6× lower offset drift, and guaranteed latch-up survival-critical for factory automation and automotive body electronics.

FAQ
What is the maximum operating junction temperature for TS952IYD?
The absolute maximum junction temperature is 150 °C. At rated 125 °C ambient and 125 °C/W thermal resistance, continuous dissipation must remain below 320 mW to avoid exceeding this limit. Derating curves in DS1256 Rev 13 confirm safe operation up to 125 °C ambient with 200 mW typical power draw.
Can TS952IYD drive capacitive loads directly?
Yes, it remains stable with up to 100 pF capacitive load at unity gain, as verified by 60° phase margin in DS1256. For loads >100 pF, a 10–50 Ω series resistor at the output is recommended to isolate capacitance and preserve stability without degrading bandwidth.
Is TS952IYD qualified for automotive applications?
No-TS952IYD is an industrial-grade part rated for −40 °C to +125 °C. Automotive-qualified equivalents include TS952IYDT (SO8) and TS952IYPT (TSSOP8), both certified to AEC-Q100 Grade 2 and screened per AEC-Q001/Q002.
How does the input bias current affect high-impedance sensor interfaces?
Input bias current is 35–100 nA (typ/max at 25 °C), rising to 200 nA over temperature. When interfacing with >1 MΩ source impedances, this introduces ≤200 µV of additional offset error-manageable with guard traces and low-leakage PCB materials, but warrants calibration in sub-mV precision systems.
