Product details
Overview
TS952IDT 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 product, 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 supports industrial signal conditioning and portable audio buffering in SO8 package.
For engineers reviewing the TS952IDT datasheet, TS952IDT pinout, TS952IDT application, or TS952IDT equivalent, this page provides verified pin functions, rail-to-rail performance context, real-world use cases in medical instrumentation and DAC buffering, and validated alternative options with documented electrical differences.
Technical Context
The TS952IDT integrates two independent high-speed op-amps on a single die, each featuring 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 BiCMOS process enables low input bias current (35–200 nA) while maintaining 80 dB CMRR and 80 dB SVR across 2.7–12 V supply.
Designed for low-voltage precision analog signal paths, it sustains stable unity-gain operation with ≥60° phase margin (RL = 600 Ω, CL = 100 pF) and delivers 0.01% THD at 10 kHz with 4 Vpk-pk output into 10 kΩ - critical for audio and sensor front-end fidelity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 12 V - supports single-supply battery-powered systems down to 2.7 V and industrial rails up to 12 V without level-shifting. |
| Gain-Bandwidth Product | 3 MHz - enables stable closed-loop gain ≥10 at 300 kHz, suitable for anti-aliasing and reconstruction filters. |
| Slew Rate | 1 V/µs - ensures ≤3.14 µs full-scale settling for 10 V step, adequate for audio line drivers and sensor amplification. |
| Input Offset Voltage | 6–8 mV (max) - limits DC error to <±8 mV in unity-gain buffer configurations, acceptable for non-precision signal chains. |
| Supply Current per Amp | 0.95 mA (typ) at 5 V - enables dual-amplifier operation under 2 mA total, ideal for power-constrained portable designs. |
| Output Voltage Swing | Within 100 mV of rails (VOL = 80 mV, VOH = 4.7 V @ 5 V, RL = 600 Ω) - maximizes dynamic range in single-supply 3.3 V or 5 V systems. |
| Common-Mode Rejection | 50–80 dB - suppresses supply noise and ground bounce in mixed-signal PCB layouts with shared analog/digital grounds. |
Pinout & Package
TS952IDT is housed in an 8-pin SOIC (SO8) package with 1.27 mm pitch, 4.9 mm × 6.0 mm body, and standard JEDEC MS-012AC outline. Thermal resistance junction-to-ambient is 125 °C/W, supporting continuous operation at up to +125 °C ambient with appropriate PCB copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Amplifier 1) | Accepts differential input signal referenced to non-inverting input; rail-to-rail common-mode range allows direct connection to 0 V or VCC in single-supply configs. |
| 2 | Non-inverting input (Amplifier 1) | Reference node for Amplifier 1; matched input bias current minimizes offset drift when used with equal source impedances. |
| 3 | Output (Amplifier 1) | Delivers rail-to-rail output swing; capable of sourcing/sinking 10 mA short-circuit current, enabling direct drive of 600 Ω loads. |
| 4 | VCC− / GND | Ground reference for dual-supply operation or system ground in single-supply mode; must be low-impedance to maintain PSRR. |
| 5 | VCC+ | Positive supply rail (2.7–12 V); decoupling capacitor (100 nF) required within 5 mm to ensure stability and noise immunity. |
| 6 | Non-inverting input (Amplifier 2) | Independent input for second amplifier; electrically isolated from Amp1 - enables dual-channel signal processing without crosstalk. |
| 7 | Inverting input (Amplifier 2) | Second differential input pair; identical specs to Pin 1 - permits matched filter or instrumentation amp topologies. |
| 8 | Output (Amplifier 2) | Second rail-to-rail output; shares same supply pins (4, 5) but maintains independent small-signal behavior up to 3 MHz. |
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 networks in single-supply sensor interfaces. |
| Rail-to-rail output voltage swing | Drives within 100 mV of supply rails at 600 Ω - preserves >95% of available voltage headroom for maximum SNR in low-voltage systems. |
| High-speed performance | 3 MHz GBW and 1 V/µs slew rate - supports bandwidth-critical applications like active filters and fast-settling DAC buffers. |
| Low quiescent current | 0.95 mA per amplifier at 5 V - enables dual-opamp functionality in battery-operated devices with multi-day runtime. |
| Latch-up immunity | Rated for 200 mA - prevents destructive failure during transient overvoltage or ESD events in harsh industrial 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 |
|---|---|---|---|
| LMV358IDR | Lower GBW (1 MHz), higher input offset (7 mV max), no latch-up immunity rating | Not qualified for automotive or extended-temp industrial use; limited to commercial-grade 0–70 °C systems | Choose when cost is primary constraint and 3 MHz bandwidth is unnecessary; verify thermal derating above 85 °C. |
| MCP6022-I/SN | Higher input bias current (1 pA typ), lower supply current (170 µA), wider temp range (−40 to +125 °C) | Better for ultra-low-power sensor nodes but lacks 1 V/µs slew rate needed for audio transients | Select for battery-powered IoT sensors requiring nanoamp bias; avoid for DAC buffering or headphone drive where speed matters. |
Compared with LMV358IDR and MCP6022-I/SN, TS952IDT uniquely balances 3 MHz bandwidth, 1 V/µs slew rate, rail-to-rail I/O, and 125 °C operation - making it optimal for industrial DAC interfaces and portable medical audio where both speed and ruggedness are mandatory.

FAQ
What is the maximum operating junction temperature for TS952IDT?
The absolute maximum junction temperature is 150 °C, with thermal resistance junction-to-ambient rated at 125 °C/W for the SO8 package. At 125 °C ambient and 1.4 mA total supply current, power dissipation remains below 100 mW - well within safe thermal margins when mounted on 1-in² 2-oz copper.
Does TS952IDT support dual-supply operation?
Yes - TS952IDT operates with split supplies (e.g., ±2.5 V to ±6 V) using Pin 4 as VCC− and Pin 5 as VCC+. The rail-to-rail input range extends to VCC− − 0.2 V and VCC+ + 0.2 V, enabling true bipolar signal handling without external level shifters.
Can TS952IDT drive capacitive loads directly?
Stable with ≤100 pF capacitive loads at unity gain, as confirmed by 60° phase margin in the datasheet. For larger loads (e.g., LCD bias or cable drivers), a 10–100 Ω series resistor between output and capacitance restores stability without degrading bandwidth significantly.
Is TS952IDT pin-compatible with other dual op-amps in SO8?
No - TS952IDT uses a non-standard pinout: Amp1 inputs on Pins 1–2, Amp1 output on Pin 3, ground on Pin 4, VCC on Pin 5, Amp2 inputs on Pins 6–7, and Amp2 output on Pin 8. This differs from industry-standard SO8 dual op-amps (e.g., LM358, TL072), requiring PCB layout revision for replacement.
