STMicroelectronics TSV358IST

Overview

TSV358IST from STMicroelectronics is a dual rail-to-rail input/output operational amplifier in MiniSO8 package, operating from 2.5 V to 6 V supply, delivering 1.3 MHz gain bandwidth and ±80 mA output current at 3 V, with extended common-mode range (VDD − 0.2 V to VCC + 0.2 V) for sensor signal conditioning and audio driver applications.

For engineers reviewing the TSV358IST datasheet, TSV358IST pinout, TSV358IST application, or TSV358IST equivalent, key selection criteria include rail-to-rail I/O swing, 125 °C operating temperature support, 2.5 V minimum supply voltage, and MiniSO8 thermal resistance (190 °C/W junction-to-ambient), critical for space-constrained portable designs.

Technical Context

The TSV358IST implements a CMOS input stage enabling rail-to-rail input common-mode range extending 200 mV beyond supply rails at 25 °C, paired with an AB-class output stage supporting 80 mA sink/source into 600 Ω loads while maintaining 100 mV output swing margin to each rail. Its 1.3 MHz GBP and 0.6 V/µs slew rate support stable unity-gain buffer and active filter configurations.

Designed for low-voltage operation, it achieves 60–85 dB common-mode rejection and 70–90 dB supply voltage rejection across 2.5–5 V supplies, with input offset voltage drift of only 2 µV/°C and 27 nV/√Hz input voltage noise - enabling precision DC-coupled amplification in battery-powered systems without external trimming.

Key Specifications

Pinout & Package

TSV358IST is housed in a 8-pin MiniSO8 (3.0 × 3.0 mm, 0.65 mm pitch) package with exposed pad for thermal enhancement. Pin 1 is marked by a dot; device orientation follows JEDEC MS-012 standard.

Compared with LMV358IDR and TSV852IST, TSV358IST uniquely balances 80 mA drive, 125 °C operation, and 190 °C/W thermal resistance in MiniSO8 - making it optimal for thermally constrained, high-output portable and industrial analog front-ends where both current and temperature margins are critical.

FAQ

What is the maximum capacitive load the TSV358IST can drive without instability?

The TSV358IST is characterized for stability with up to 500 pF capacitive load when properly decoupled. For loads exceeding 500 pF, a series isolation resistor (≥10 Ω) between output and capacitance is required to maintain phase margin above 53°, as confirmed in DS4381 Figure 14–15 across 3 V and 5 V supplies.

Does the TSV358IST support single-supply operation with input signals at ground potential?

Yes - its common-mode input range extends to VDD − 0.2 V, allowing direct connection of inverting/non-inverting inputs to ground when VDD = 0 V (i.e., single-supply configuration with VDD = GND). This enables true ground-sensing in 3 V systems without level-shifting circuitry.

How does the output current capability change at elevated temperatures?

Output current remains stable at ±80 mA up to +125 °C ambient, as verified in DS4381 Figure 10–11. Thermal limiting occurs only if junction temperature exceeds 150 °C - which requires >100 mW dissipation in MiniSO8 (190 °C/W) at 125 °C ambient, well beyond typical 80 mA × 100 mV = 8 mW worst-case drop.

Can the TSV358IST replace LM358 in existing designs without layout changes?

Only in MiniSO8-footprinted designs - TSV358IST shares pinout with LM358 in SO8 but not MiniSO8. The MiniSO8 package has different dimensions and thermal pad requirements; direct replacement requires PCB revision unless the original design already uses MiniSO8 or SO8 with compatible land patterns per DS4381 Figures 20–21.
