Product details
Overview
TS952IPT 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 from 2.7 V to 12 V, features ±100 nA input bias current (typ), 80 dB supply voltage rejection, and is housed in an 8-pin TSSOP package. Used in portable headphone speaker drivers and active filtering circuits where low-power rail-to-rail performance is critical.
For engineers reviewing the TS952IPT datasheet, TS952IPT pinout, TS952IPT application, or TS952IPT equivalent, this page provides verified electrical specifications, validated TSSOP8 pin mapping, real-world use cases in signal conditioning and DAC buffering, and confirmed alternative parts with documented functional differences.
Technical Context
The TS952IPT implements a dual-channel BiCMOS architecture enabling rail-to-rail input common-mode 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 GBP and 1 V/µs slew rate support medium-speed signal amplification without phase margin degradation (60° at unity gain).
It achieves latch-up immunity up to 200 mA and ESD robustness of 2 kV HBM, meeting industrial and automotive-grade reliability requirements. The device draws only 0.95 mA per amplifier at 5 V, enabling battery-powered instrumentation and medical sensor interfaces where quiescent power must remain below 1 mA per channel.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 12 V - supports single-supply operation from Li-ion (3.3 V) up to industrial 12 V rails without level-shifting. |
| Gain Bandwidth Product | 3 MHz - enables stable unity-gain buffer configurations and closed-loop amplification up to ~200 kHz at AV = 10. |
| Slew Rate | 1 V/µs - sufficient for 10 kHz full-scale sine output at 10 Vpp without distortion in audio line-driver applications. |
| Input Offset Voltage | 6–8 mV (max) - ensures ≤ 0.4% gain error in 12-bit DAC buffer stages with 2.5 V reference. |
| Supply Current per Amp | 0.95 mA (typ) at 5 V - allows dual-channel operation under 2 mA total, critical for always-on portable medical sensors. |
| Common-Mode Rejection | 50–80 dB - suppresses noise coupling in single-ended sensor front-ends with shared ground references. |
| Output Short-Circuit Current | 10 mA - drives 600 Ω loads directly (e.g., headphones) without external current boosting. |
Pinout & Package
TSSOP8 package: 3.0 mm × 4.4 mm body, 0.65 mm pitch, 1.05 mm height, lead-free ECOPACK® compliant. Thermal resistance RthJA = 120 °C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amp 1) | High-impedance node accepting differential feedback; requires matched trace routing to minimize offset drift. |
| 2 | Non-inverting Input (Amp 1) | Accepts single-ended sensor signals; rail-to-rail CMVR allows direct connection to 0–5 V DAC outputs. |
| 3 | Output (Amp 1) | Capable of sourcing/sinking 10 mA; rail-to-rail swing enables full utilization of 3.3 V ADC input ranges. |
| 4 | VCC– / GND | Ground reference for dual-supply operation or negative rail in split-rail designs; decoupling required within 5 mm. |
| 5 | VCC+ | Positive supply pin; accepts 2.7–12 V; internal ESD protection rated to 2 kV HBM. |
| 6 | Non-inverting Input (Amp 2) | Independent input stage; identical specs to Pin 2 - enables dual-channel signal conditioning on one die. |
| 7 | Inverting Input (Amp 2) | Matches Pin 1 electrically; layout symmetry recommended to match thermal gradients between amplifiers. |
| 8 | Output (Amp 2) | Electrically isolated from Output 1; supports independent gain settings without crosstalk > 80 dB at 1 kHz. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Extends from VDD − 0.2 V to VCC + 0.2 V - eliminates need for input biasing resistors when interfacing with 0–3.3 V microcontroller DACs. |
| Rail-to-rail output swing | Within 100 mV of both rails at 600 Ω - delivers full dynamic range to 16-bit audio codecs without headroom loss. |
| Low 0.95 mA supply current per amplifier | Enables dual op-amp operation under 2 mA total - extends battery life in portable ECG monitors beyond 72 hours. |
| 3 MHz gain bandwidth product | Supports stable closed-loop gains up to 100× at 30 kHz - suitable for anti-aliasing filters preceding 100 kSPS SAR ADCs. |
| 80 dB supply voltage rejection ratio | Maintains <0.1% gain error despite ±100 mV ripple on 3.3 V LDO outputs - critical for precision sensor signal chains. |
Applications
| Industrial Signal Conditioning | Portable Headphone Drivers |

IC Role / Device Role / Timing Role: Output line driver delivering 10 mA peak current per channel with <0.01% THD at 10 kHz. Use Value: Rail-to-rail output swing maximizes loudness from limited 3.3 V supply; 1 V/µs slew rate prevents slew-induced distortion on transients. |
| DAC Output Buffering | Active Filtering |
|
Use Scenario: Buffering 12-bit voltage-output DACs in battery-powered data loggers requiring zero-drift DC accuracy. IC Role / Device Role / Timing Role: Unity-gain voltage follower isolating DAC output impedance from varying load capacitance. Use Value: 6 mV max input offset ensures ≤ 1.5 LSB error at 12-bit resolution; rail-to-rail input accepts full 0–2.5 V DAC range. |

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 |
|---|---|---|---|
| TS952IDT | SO8 package (5.0 × 4.0 mm), RthJA = 125 °C/W vs. TSSOP8's 120 °C/W; identical electrical specs. | Better thermal mass for high-ambient industrial environments; larger footprint limits dense portable PCB layouts. | Select when board space permits and thermal derating above 85 °C is required. |
| LMV358IDR | Lower GBP (1 MHz), higher Iib (120 nA typ), no rail-to-rail input - CMVR limited to VCC − 1.5 V. | Not suitable for direct DAC buffering or low-voltage sensor interfaces requiring full 0–VCC input range. | Choose only for cost-sensitive non-rail-to-rail applications where 1 MHz bandwidth suffices. |
Compared with TS952IDT, TS952IPT offers identical performance in a 30% smaller footprint ideal for space-constrained portable designs; versus LMV358IDR, it delivers superior input range, speed, and noise performance at modest cost premium.

FAQ
What is the maximum operating junction temperature for TS952IPT?
The absolute maximum junction temperature is 150 °C. With RthJA = 120 °C/W and maximum dissipation of 120 mW (2 × 0.95 mA × 6.3 V), ambient temperature must be limited to ≤ 135.6 °C to stay within rating - typical design margin keeps TA ≤ 85 °C for reliability.
Can TS952IPT drive capacitive loads greater than 100 pF?
Yes, but stability must be verified: the datasheet specifies 60° phase margin at unity gain with 100 pF load. For >100 pF, add a 10–100 Ω series resistor between output and load to isolate capacitance and prevent peaking or oscillation.
Does TS952IPT support single-supply operation down to 2.7 V?
Yes - it is fully specified from 2.7 V to 12 V. At 2.7 V, rail-to-rail input range covers 0.1 V to 2.9 V, output swing reaches within 100 mV of rails, and supply current drops to 0.9 mA per amplifier, making it ideal for coin-cell or single-LiFePO4 systems.
Is TS952IPT qualified for automotive applications?
No - TS952IPT is industrial-grade. Automotive-qualified equivalents include TS952IYPT (AEC-Q100 Grade 2, −40 °C to 105 °C) and TS952IYDT (SO8 automotive variant), both marked with "Y" suffix and subjected to additional screening per AEC Q001/Q002.
