Product details
Overview
TSV358IPT from STMicroelectronics is a dual rail-to-rail input/output operational amplifier in TSSOP-8 package, designed for low-voltage portable systems. It operates from 2.5 V to 6 V, delivers 80 mA output current per channel, achieves 1.3 MHz gain bandwidth at 3 V, and supports extended common-mode input range (VDD − 0.2 V to VCC + 0.2 V) - enabling direct sensor interfacing and headphone driver applications in battery-powered devices.
For engineers reviewing the TSV358IPT datasheet, TSV358IPT pinout, TSV358IPT application, or TSV358IPT equivalent, key selection criteria include its rail-to-rail I/O performance at 3 V supply, −40 °C to +125 °C operating temperature, 27 nV/√Hz input voltage noise, 0.6 V/µs slew rate, and compatibility with 32 Ω loads - critical for audio buffering and precision signal conditioning in space-constrained designs.
Technical Context
The TSV358IPT implements a CMOS input stage with rail-to-rail input common-mode range extending 200 mV beyond supply rails and rail-to-rail output swing within 100 mV of each rail under 600 Ω load. Its internal architecture supports stable operation with capacitive loads up to 500 pF without external compensation.
It features low quiescent current (650 µA per amplifier at 3 V), high open-loop gain (92 dB at 3 V), and robust ESD protection (2 kV HBM). The device maintains consistent offset voltage drift (2 µV/°C) and THD (0.01 %), making it suitable for DC-coupled and low-distortion AC signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.5 V to 6 V - enables direct use with single-cell Li-ion (3.0–3.7 V) and two-cell alkaline (3.0 V) power sources. |
| Gain Bandwidth Product | 1.3 MHz at VCC = 3 V - supports unity-gain stable active filters and audio preamplifiers up to ~100 kHz. |
| Output Current | ±80 mA per channel - drives 32 Ω headphones directly without external buffer stages. |
| Input Offset Voltage | 3 mV max (TSV358), 1 mV max (TSV358A) - ensures <100 µV error in 3.3 V sensor signal chains with 10× gain. |
| Common-Mode Input Range | VDD − 0.2 V to VCC + 0.2 V - accepts inputs down to ground and up to supply rail, simplifying single-supply transducer interfacing. |
| Slew Rate | 0.6 V/µs - supports 100 kHz full-scale sine output at 6 Vpp without distortion. |
| Operating Temperature | −40 °C to +125 °C - qualified for industrial and automotive cabin electronics environments. |
Pinout & Package
TSSOP-8 (Thin Shrink Small Outline Package, 3.0 mm × 4.4 mm, 0.65 mm pitch) with exposed thermal pad (non-electrical). Pin 1 marked by dot; pins numbered counterclockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel A) | High-impedance node accepting differential signal reference; requires matched layout for optimal CMRR. |
| 2 | Non-inverting Input (Channel A) | Accepts sensor or reference signal; rail-to-rail common-mode range allows direct connection to grounded sensors. |
| 3 | Output (Channel A) | Capable of sourcing/sinking ±80 mA; stable into 500 pF capacitive load without oscillation. |
| 4 | VDD (Ground) | Power return path; must be low-inductance connection to minimize noise coupling between channels. |
| 5 | Output (Channel B) | Independent output stage; shares same supply rails but electrically isolated from Channel A. |
| 6 | Non-inverting Input (Channel B) | Second independent input; identical specs to Pin 2 - enables dual-sensor or stereo signal processing. |
| 7 | Inverting Input (Channel B) | Matches Pin 1 functionality; layout symmetry critical when using both amplifiers in feedback networks. |
| 8 | VCC (Supply) | 2.5–6 V single supply input; decoupling capacitor (100 nF X7R) required within 2 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in 3.3 V systems - output swings to within 100 mV of VCC/VDD with 600 Ω load. |
| Extended Vicm | Input accepts signals 200 mV below VDD and 200 mV above VCC at 25 °C - eliminates level-shifting for ground-referenced sensors. |
| 32 Ω Load Drive | Direct headphone interface without external MOSFET buffer - reduces BOM count and PCB area in portable audio. |
| 500 pF Capacitive Load Stability | No external compensation needed when driving ADC input filters or long PCB traces - improves design robustness. |
| −40 °C to +125 °C Operation | Validated performance across full industrial temperature range - suitable for engine control modules and motor drive feedback circuits. |
Applications
| Audio Signal Path | Sensor Interface |

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 | Wider supply range (2.7–5.5 V); higher input bias current (150 nA vs. 125 nA typ); no extended Vicm. | Limited to 5 V systems; less suitable for sub-3 V sensor nodes or ground-referenced inputs. | Prefer TSV358IPT where 2.5 V operation or extended common-mode range is required. |
| TSV852IST | Higher GBP (12 MHz), lower noise (19 nV/√Hz), but higher ICC (1.1 mA per amp) and narrower Vicm (VDD to VCC). | Better for high-speed filtering but unsuitable for low-power battery applications or rail-to-rail input sensing. | Choose TSV358IPT for ultra-low-power, wide-Vicm, cost-sensitive industrial designs. |
Compared with LMV358IDR and TSV852IST, the TSV358IPT uniquely balances 2.5 V operation, extended Vicm, 80 mA drive, and 650 µA quiescent current - making it optimal for space- and power-constrained dual-channel signal conditioning where input headroom and output strength are jointly critical.

FAQ
Is TSV358IPT pin-compatible with LM358?
No. TSV358IPT uses TSSOP-8 packaging with different pin assignments than the SO-8 LM358. While both are dual op-amps, TSV358IPT has rail-to-rail I/O and extended common-mode range - requiring PCB layout revision and schematic updates for replacement. Pin mapping differs for inverting/non-inverting inputs and outputs.
What is the maximum capacitive load the TSV358IPT can drive stably?
The TSV358IPT is specified stable with up to 500 pF capacitive load without external compensation, as confirmed in DS4381 Rev 9 Section 2. This applies across the full operating temperature range and supply voltage (2.5–6 V), making it suitable for driving ADC input filters and long trace interconnects.
Does TSV358IPT support true single-supply operation with inputs at ground?
Yes. At 25 °C, its common-mode input range extends to VDD − 0.2 V - allowing inputs down to −0.2 V when VDD = 0 V (i.e., ground-referenced configuration). This enables direct interfacing with grounded sensors like thermistors and strain gauges without level-shifting circuitry.
How does the TSV358IPT differ from the TSV358A variant?
The TSV358A offers improved input offset voltage (1 mV max vs. 3 mV max for TSV358) and tighter offset drift (2 µV/°C remains unchanged), achieved via enhanced trimming. Both share identical pinout, package, supply range, output drive, and temperature rating - making TSV358A preferred for precision DC-coupled applications.
