STMicroelectronics TSV612ID

Overview

TSV612ID from STMicroelectronics is a dual rail-to-rail input/output CMOS operational amplifier optimized for ultra-low-power, low-voltage sensor signal conditioning. It delivers 120 kHz gain bandwidth, 10 µA supply current per amplifier at 5 V, and operates from 1.5 to 5.5 V - enabling use in battery-powered smoke detectors and portable medical instrumentation.

For engineers reviewing the TSV612ID datasheet, TSV612ID pinout, TSV612ID application, or TSV612ID equivalent, key selection criteria include its rail-to-rail I/O swing (≤35 mV from rails), 1 pA typical input bias current, -40 to 85 °C industrial temperature range, and MiniSO-8 package compatibility with space-constrained PCB layouts.

Technical Context

The TSV612ID employs complementary PMOS/NMOS input stages to achieve true rail-to-rail input common-mode range (VCC− −0.1 V to VCC+ +0.1 V) without phase reversal. Its unity-gain-stable architecture supports active filtering and precision buffering across the full 1.5–5.5 V supply range.

Output drive capability is specified for 10 kΩ loads with VOH ≤50 mV below VCC and VOL ≤50 mV above VCC−, while maintaining 62° phase margin and 10 dB gain margin at 5 V. Input offset voltage is guaranteed ≤2 mV (A-grade) and drift is 2 µV/°C.

Key Specifications

Pinout & Package

TSV612ID is housed in an 8-pin MiniSO-8 package (3.0 × 4.9 mm, 0.65 mm pitch), offering improved thermal performance (R_thJA = 190 °C/W) and board-area efficiency over standard SO-8.

FAQ

What is the maximum capacitive load the TSV612ID can drive without external compensation?

The TSV612ID is stable driving up to 100 pF capacitive loads in unity-gain follower configuration, as verified in the datasheet's Figure 19 and Section 3.4. For loads exceeding 100 pF, a series resistor (value selected per Figure 19) must be added between the output and load to maintain phase margin ≥60° and prevent oscillation.

Does the TSV612ID support true rail-to-rail input at 1.5 V supply?

Yes - the input common-mode voltage range extends from (VCC−) −0.1 V to (VCC+) +0.1 V across the full 1.5–5.5 V supply range, including at 1.5 V. This is confirmed in Table 2 (Operating Conditions) and Section 3.2, which states no phase reversal occurs and performance remains specified down to 1.5 V.

How does the input offset voltage drift affect long-term accuracy in medical sensor applications?

The TSV612ID exhibits a guaranteed input offset voltage drift of 2 µV/°C, meaning a 40 °C ambient shift introduces ≤80 µV additional error. Combined with ≤2 mV max initial V_os, total DC error stays under 2.1 mV - well within acceptable limits for 12-bit ECG or temperature measurement front-ends operating over -40 to 85 °C.

Is the MiniSO-8 package of TSV612ID RoHS-compliant and halogen-free?

Yes - the TSV612ID uses ST's ECOPACK®2-compliant MiniSO-8 package, certified RoHS-compliant and halogen-free per IEC 61249-2-21. Full environmental compliance documentation, including material declarations and test reports, is available on ST's official website under ECOPACK® resources.
