Product details
Overview
TSV358IDT from STMicroelectronics is a dual rail-to-rail input/output operational amplifier in SO8 package, operating from 2.5 V to 6 V supply, delivering 1.3 MHz gain bandwidth and 80 mA output current per channel at 3 V, with extended common-mode range (VDD − 0.2 V to VCC + 0.2 V) and −40 °C to +125 °C temperature rating - used in battery-powered audio drivers and sensor signal conditioning circuits.
For engineers reviewing the TSV358IDT datasheet, TSV358IDT pinout, TSV358IDT application, or TSV358IDT equivalent, key selection factors include rail-to-rail I/O swing, 80 mA drive capability into 32 Ω loads, low 650 µA supply current per amplifier at 3 V, and guaranteed operation across automotive-grade temperature extremes.
Technical Context
The TSV358IDT implements a CMOS-input, rail-to-rail output op-amp architecture optimized for low-voltage portable systems. Its input stage supports common-mode voltage beyond rails by ±200 mV at 25 °C, while output swings within 100 mV of each rail under 600 Ω load - enabling full dynamic range utilization in single-supply 3 V systems.
It features internal compensation for unity-gain stability with up to 500 pF capacitive load, delivers 0.6 V/µs slew rate, and maintains 80 dB CMRR and 90 dB SVR over its full operating range - making it suitable for precision DC-coupled amplification and active filtering where supply rejection and offset drift matter.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.5 V to 6 V - enables direct use in Li-ion (3.0–4.2 V), USB-powered (5 V), and dual-cell alkaline (3 V) systems without LDO pre-regulation. |
| Gain Bandwidth Product | 1.3 MHz at VCC = 3 V - supports stable closed-loop gain ≥10 up to ~130 kHz, sufficient for anti-aliasing filters and audio preamps. |
| Output Current | ±80 mA - drives 32 Ω headphone loads directly or 600 Ω sensors with <100 mV headroom to rails. |
| Input Offset Voltage | 3 mV max (TSV358), 1 mV max (TSV358A) - ensures ≤3 mV error in 1 V full-scale sensor interfaces without trimming. |
| Common-Mode Range | VDD − 0.2 V to VCC + 0.2 V - allows input signals to exceed supply rails slightly, easing level-shifting in mixed-supply systems. |
| Quiescent Current | 650 µA per amplifier at 3 V - enables dual-channel operation at <1.3 mA total, critical for multi-day battery life in portable devices. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive, industrial control, and ruggedized portable equipment. |
Pinout & Package
TSV358IDT is housed in an 8-pin SO8 (Small Outline Integrated Circuit) package with standard 1.27 mm pitch, 5.0 mm × 4.0 mm body, and 1.75 mm height - RoHS-compliant and ECOPACK® certified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (A) | High-impedance node for feedback network connection; accepts signals from VDD − 0.2 V to VCC + 0.2 V. |
| 2 | Non-inverting Input (A) | High-Z input for reference or sensor signal; same extended common-mode range as Pin 1. |
| 3 | Output (A) | Rail-to-rail output capable of sourcing/sinking 80 mA; swings within 100 mV of VDD/VCC with 600 Ω load. |
| 4 | VDD (Ground) | Low-side supply rail - connected to system ground in single-supply configurations. |
| 5 | Non-inverting Input (B) | Second independent input channel; identical specs and biasing to Pin 2. |
| 6 | Inverting Input (B) | Second independent input channel; identical specs and biasing to Pin 1. |
| 7 | Output (B) | Second rail-to-rail output; electrically isolated from Output A, supports dual-path signal processing. |
| 8 | VCC (Supply) | Positive supply rail - accepts 2.5–6 V; supplies both amplifiers with shared quiescent current path. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full-swing signal handling in 3 V single-supply systems without level-shifting circuitry. |
| Extended Common-Mode Range | Accepts inputs 200 mV beyond supply rails - simplifies interfacing with DACs or sensors operating at different reference voltages. |
| High Output Drive | 80 mA per channel drives 32 Ω headphones or 600 Ω instrumentation loads without external buffers. |
| Low Power Operation | 650 µA per amplifier at 3 V allows dual-channel analog front-end design with sub-1.3 mA total supply current. |
| Wide Temperature Range | Guaranteed performance from −40 °C to +125 °C supports deployment in automotive engine compartments and industrial PLCs. |

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 | Higher 1.8 MHz GBW but only 45 mA output drive; 1.25 V minimum supply; no extended Vicm beyond rails. | Better for higher-frequency filtering but unsuitable for 32 Ω headphone loads or rail-exceeding sensor inputs. | Choose LMV358IDR when bandwidth >1.3 MHz is required and output load >600 Ω; avoid for low-Vcc headphone or wide-Vicm apps. |
| TSV852IST | Enhanced precision: 0.4 mV max Vio, 0.5 µV/°C drift, 2.4 MHz GBW; MiniSO8 package; 1.5–5.5 V supply. | Superior DC accuracy and speed, but lower 60 mA output drive and narrower supply range excludes 6 V operation. | Choose TSV852IST for precision sensor front-ends needing <0.5 mV offset and <1 µV/°C drift; not for 6 V or high-current loads. |
Compared with LMV358IDR and TSV852IST, TSV358IDT uniquely balances 80 mA drive, rail-exceeding Vicm, 6 V max supply, and −40 °C to +125 °C operation - making it optimal for robust, low-voltage, high-output analog stages where precision and power efficiency coexist.

FAQ
What is the maximum capacitive load the TSV358IDT can drive stably?
The TSV358IDT is internally compensated for unity-gain stability with up to 500 pF capacitive load, as confirmed in the datasheet's absolute maximum ratings table. Driving larger loads requires external isolation resistance (e.g., 10–100 Ω in series with the output) to maintain phase margin above 53° and prevent oscillation.
Does TSV358IDT support true single-supply operation with input signals near ground?
Yes - its common-mode input range extends to VDD − 0.2 V at 25 °C, allowing inputs down to −200 mV relative to ground in single-supply configurations. This enables direct interfacing with grounded sensors or DACs without level-shifting circuitry, provided input current remains within ±1 mA limits.
How does the TSV358IDT differ from the TSV358AIDT variant?
The TSV358AIDT features tighter input offset voltage (1 mV max vs. 3 mV max for TSV358IDT) and lower offset drift (2 µV/°C typ.), achieved via enhanced laser trimming. Both share identical pinout, package, supply range, output drive, and temperature rating - making TSV358AIDT preferable for precision DC-coupled applications where offset error must be minimized.
Can TSV358IDT be used in automotive under-hood applications?
Yes - the TSV358IDT is rated for −40 °C to +125 °C operating temperature and meets ST's industrial reliability standards. While not AEC-Q100 qualified (that status applies to the "IY" automotive-grade variants like TSV358IYDT), its thermal and electrical specs fully support under-hood use in non-safety-critical subsystems such as cabin climate control or infotainment power management.
