STMicroelectronics TSV992IYDT

Overview

TSV992IYDT from STMicroelectronics is a dual rail-to-rail input/output operational amplifier optimized for low-voltage, low-power applications. It delivers 20 MHz gain-bandwidth at 4 V/V minimum stable gain, 1.5 mV max input offset voltage (A grade), 820 µA typical supply current per channel, and operates from 2.5 V to 5.5 V - enabling precision signal conditioning in battery-powered medical sensors and automotive body control modules.

For engineers reviewing the TSV992IYDT datasheet, TSV992IYDT pinout, TSV992IYDT application, or TSV992IYDT equivalent, key selection criteria include its rail-to-rail I/O swing at 2.5 V supply, stability requirement (gain ≥ 4 or ≤ −3), ultra-low 1 pA typical input bias current, and SO8 packaging with automotive-grade −40 °C to 125 °C operation.

Technical Context

The TSV992IYDT employs a high-speed, low-power CMOS input stage enabling 1 pA typical input bias current and rail-to-rail common-mode input range (VCC− − 0.1 V to VCC+ + 0.1 V). Its internal compensation ensures phase margin ≥ 45° only when configured for gain ≥ 4 (non-inverting) or ≤ −3 (inverting), making unity-gain follower use require external stabilization.

It features a 20 MHz gain-bandwidth product with 10 V/μs slew rate, 75 dB typical CMRR at 25 °C, and 82 dB typical SVR - supporting accurate amplification of low-level sensor signals in noisy automotive and portable environments without requiring external trimming.

Key Specifications

Pinout & Package

TSV992IYDT is supplied in an SO8 package (8-pin small outline integrated circuit) with exposed pad not internally connected. Pin 1 is marked by a beveled corner or dot; the device uses standard SO8 footprint with 1.27 mm pitch.

Equivalent & Alternatives

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

Compared with TSV992IYDT, TSV912IDT trades 12 MHz bandwidth for guaranteed unity-gain stability and lower quiescent current, while LMV358QDRQ1 reduces supply current by 82% but sacrifices 95% of gain-bandwidth and loses rail-to-rail input capability - making TSV992IYDT optimal for high-fidelity, medium-speed sensor interfaces demanding both precision and speed.

FAQ

Can TSV992IYDT be used in unity-gain buffer configuration?

No - TSV992IYDT is not unity-gain stable and requires minimum closed-loop gain of 4 (non-inverting) or −3 (inverting) for phase margin ≥45°. To implement a buffer, add a 10–100 Ω series resistor between output and load, or use the TSV912IDT which is unity-gain stable and pin-compatible in SO8.

What is the maximum capacitive load the TSV992IYDT can drive without oscillation?

At gain ≥4, TSV992IYDT remains stable with up to 100 pF capacitive load per datasheet Figure 8–9. For larger loads (e.g., >200 pF), add a 10–47 Ω isolation resistor in series with the output or use a feedback capacitor (e.g., 2–10 pF across Rf) to suppress peaking, as detailed in Section 5.1 of DS4975.

Does the exposed pad on the SO8 package need to be connected?

No - the exposed pad on TSV992IYDT's SO8 package is not internally connected and may be left floating or tied to VCC− for improved thermal dissipation. It must not be connected to any other potential, as confirmed in DS4975 Section 6.5 footnote.

How does the 1.5 mV max input offset voltage impact 12-bit ADC interfacing at 3.3 V full scale?

With 3.3 V full scale, a 12-bit ADC has 0.8 mV LSB. A 1.5 mV max Vio introduces up to ±1.875 LSB of uncalibrated error - acceptable for many industrial sensors but requiring either calibration or use of the lower-offset TSV992AIDT (1.5 mV max at 25 °C, 3 mV over temperature) if tighter DC accuracy is needed.
