STMicroelectronics TSV358IYDT

Overview

TSV358IYDT 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) for sensor signal conditioning and audio driver applications.

For engineers reviewing the TSV358IYDT datasheet, TSV358IYDT pinout, TSV358IYDT application, or TSV358IYDT equivalent, this device supports low-voltage portable systems requiring rail-to-rail swing, high stability into 500 pF loads, and operation across −40 °C to +125 °C industrial temperature range.

Technical Context

The TSV358IYDT implements a CMOS input stage enabling rail-to-rail input voltage range extending 200 mV beyond supply rails at 25 °C, and an output stage capable of swinging within 100 mV of each rail under 600 Ω load. Its unity-gain stable architecture achieves 53° phase margin with 100 pF capacitive load.

It features 27 nV/√Hz input voltage noise, 0.42–0.6 V/µs slew rate, and 60–85 dB common-mode rejection ratio (CMRR), optimized for precision DC-coupled amplification and AC signal buffering in battery-powered systems where supply headroom is constrained.

Key Specifications

Pinout & Package

TSV358IYDT is housed in an 8-pin SO8 (Small Outline) package with standard 1.27 mm pitch, 4.9–5.0 mm width, and 6.0 mm length per ST's mechanical data (DS4381 Rev 9, Table 6). It complies with ECOPACK® environmental specifications.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual op-amp applications.

Compared with LMV358IDR, TSV358IYDT offers lower minimum supply voltage and tighter offset; versus TSV852IST, it trades bandwidth and offset for broader temperature qualification and SO8 compatibility in legacy designs.

FAQ

What is the maximum capacitive load the TSV358IYDT can drive while maintaining stability?

The TSV358IYDT is specified stable with up to 500 pF capacitive load at unity gain, per DS4381 Rev 9. This enables direct connection to LCD bias lines, long PCB traces, or piezo elements without external isolation resistors. Phase margin remains ≥53° under these conditions, verified at VCC = 3 V and 5 V with CL = 100 pF to 500 pF.

Does the TSV358IYDT support true rail-to-rail input when VCC = 2.5 V?

Yes. At VCC = 2.5 V and Tamb = 25 °C, the common-mode input range extends from VDD − 0.2 V (−0.2 V) to VCC + 0.2 V (2.7 V), confirmed in Table 2 of DS4381 Rev 9. This allows input signals to swing 200 mV beyond both supply rails, critical for single-supply transducer interfaces where sensor ground differs from system ground.

How does the output current capability change across temperature?

Output current remains stable across −40 °C to +125 °C: typical ±80 mA is maintained at all temperatures per Figure 11 (VCC = 3 V) and Figure 10 (VCC = 5 V) in DS4381 Rev 9. The device sustains this drive into 600 Ω loads without thermal shutdown, enabled by SO8's 125 °C/W R_thJA and internal current limiting.

Is the TSV358IYDT pin-compatible with standard LM358 SO8 variants?

Yes-pinout matches industry-standard dual op-amp SO8 layout (pins 1–8 as inverting input A, non-inverting input A, output A, V−, non-inverting input B, inverting input B, output B, V+). However, TSV358IYDT adds rail-to-rail I/O and extended Vicm not present in LM358, enabling drop-in upgrades in many 3 V–5 V designs without schematic changes.
