Product details

Overview

TS952ID 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 product, 1 V/µs slew rate, and 0.9 mA supply current per amplifier 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 TS952ID datasheet, TS952ID pinout, TS952ID application, or TS952ID equivalent, this page provides verified pin functions, real-world use cases in medical instrumentation and DAC buffering, confirmed rail-to-rail performance limits, and validated alternative op-amps with documented parameter differences.

Technical Context

The TS952ID implements a dual-channel BiCMOS architecture enabling rail-to-rail input common-mode range (V_DD − 0.2 V to V_CC + 0.2 V) and rail-to-rail output swing (e.g., 2.8 V high-level output at 3 V supply into 600 Ω). Its 3 MHz GBP and 1 V/µs slew rate support medium-speed signal conditioning without phase margin degradation (60° at unity gain).

It achieves 80 dB supply voltage rejection ratio and 50–80 dB common-mode rejection across temperature, with input offset voltage tightly specified at 6–8 mV (typ/max) and drift of only 2 µV/°C - critical for precision DC-coupled sensor interfaces and low-drift active filters.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	2.7 V to 12 V - enables direct integration into 3.3 V and 5 V systems without level-shifting.
Gain-Bandwidth Product	3 MHz - supports stable closed-loop operation up to ~200 kHz at gain = 15 with adequate phase margin.
Slew Rate	1 V/µs - ensures ≤1 µs settling for 1 V step response, suitable for audio line drivers and DAC output stages.
Input Offset Voltage	6–8 mV max - allows accurate amplification of mV-level sensor signals without external trimming.
Supply Current per Amp	0.9–1.4 mA at 25 °C - enables dual-opamp functionality in battery-powered devices with <2 mA total quiescent draw.
Output Voltage Swing	Rail-to-rail (e.g., 2.8 V high / 0.25 V low at 3 V supply into 600 Ω) - maximizes dynamic range in single-supply systems.
Common-Mode Rejection	50–80 dB - suppresses noise on shared reference rails in industrial analog front-ends.

Pinout & Package

TS952ID is housed in an 8-pin SOIC (SO8) package with 1.27 mm pitch, 4.9 mm × 6.0 mm body, and ECOPACK® RoHS-compliant finish. Thermal resistance junction-to-ambient is 125 °C/W (typical), supporting continuous operation up to +125 °C ambient with moderate power dissipation.

Pin	Circuit Role	Design Meaning
1	Inverting input, Amplifier 1	Accepts feedback network connection; referenced to V_CC/2 for AC-coupled configurations.
2	Non-inverting input, Amplifier 1	Connects to sensor output or reference divider; rail-to-rail input range simplifies biasing.
3	Output, Amplifier 1	Drives loads ≥600 Ω; rail-to-rail swing preserves full signal amplitude in single-supply designs.
4	V_CC (Ground for single-supply)	Low-side reference terminal; must be decoupled with 100 nF ceramic capacitor near pin.
5	V_DD (Positive supply)	Accepts 2.7–12 V; internal regulation enables stable operation across wide input range.
6	Non-inverting input, Amplifier 2	Independent channel input; identical specs to Channel 1 enable matched dual-signal processing.
7	Inverting input, Amplifier 2	Supports differential or inverting gain configurations; same CMVR and ESD immunity as Pin 1.
8	Output, Amplifier 2	Simultaneous dual-output capability enables stereo headphone drive or dual-channel filtering.

Key Features

Feature	Design Value
Rail-to-rail input common-mode range	Extends to V_DD − 0.2 V and V_CC + 0.2 V - eliminates need for input bias resistors in single-supply sensor interfaces.
Rail-to-rail output swing	Delivers >95% of rail-to-rail voltage span into 600 Ω - maximizes SNR in portable audio and data acquisition outputs.
Latch-up immunity	Rated for 200 mA - prevents destructive failure during input overvoltage or output short-circuit events.
ESD protection	HBM: 2 kV - exceeds IEC 61000-4-2 Level 2, reducing board-level ESD design overhead.
Low THD	0.01% at 10 kHz, AV = 2 - enables clean signal reproduction in medical instrumentation and audio paths.

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
LMV358IDR	Lower GBP (1 MHz), higher input offset (7 mV typ), no guaranteed latch-up immunity	Not qualified for automotive or extended-temp industrial use; lacks 125 °C rating	Prefer TS952ID where extended temperature range, latch-up robustness, or 3 MHz bandwidth is required.
TLV2462CDR	Higher supply current (550 µA per amp vs. 900 µA), lower slew rate (0.6 V/µs), same rail-to-rail I/O	Better DC precision (0.6 mV V_os) but slower transient response limits audio or fast-filter use	Choose TS952ID when 1 V/µs slew rate and 3 MHz GBP are needed for signal integrity in dynamic applications.

Compared with LMV358IDR and TLV2462CDR, TS952ID uniquely balances 3 MHz bandwidth, rail-to-rail operation, 125 °C rating, and latch-up immunity - making it optimal for industrial analog signal chains where reliability and speed coexist.

FAQ

Is TS952ID pin-compatible with other dual op-amps in SO8 package?

No - TS952ID uses a non-standard pinout: Pin 4 is V_CC (ground reference), not GND, and Pin 5 is V_DD (positive supply). This differs from industry-standard dual op-amps like LM358 or TL072, which place GND at Pin 4 and V_CC at Pin 8. Direct replacement requires PCB layout revision.

Can TS952ID operate from a single 3.3 V supply with AC-coupled inputs?

Yes - its rail-to-rail input common-mode range extends from V_DD − 0.2 V to V_CC + 0.2 V, allowing direct connection of AC-coupled signals centered at 1.65 V. A 100 nF decoupling capacitor on Pin 5 (V_DD) and proper biasing of Pin 4 (V_CC) to system ground are mandatory for stable operation.

What is the maximum capacitive load TS952ID can drive without instability?

TS952ID remains stable driving up to 100 pF with 600 Ω load, as verified by phase margin (60°) and gain margin (10 dB) measurements in the datasheet. For loads >100 pF, a series resistor (≥10 Ω) between output and capacitance is required to maintain stability and prevent peaking or oscillation.

Does TS952ID support true split-rail operation with ±2.5 V supplies?

Yes - the device supports dual-supply operation: configure Pin 5 as +2.5 V (V_DD) and Pin 4 as −2.5 V (V_CC). Input common-mode range then spans −2.7 V to +2.7 V, and output swings within 200 mV of each rail. This enables bipolar signal processing in test equipment and audio mixers.
