STMicroelectronics TSV792IYDT

Overview

TSV792IYDT from STMicroelectronics is a dual rail-to-rail input/output operational amplifier optimized for high-precision, high-bandwidth signal conditioning in automotive and industrial power management systems. It delivers 50 MHz gain bandwidth, 30 V/µs slew rate, 200 µV max input offset voltage, 1 pA typ. input bias current, and operates from 2.2 V to 5.5 V supply - enabling accurate low-side current sensing and photodiode transimpedance amplification.

For engineers reviewing the TSV792IYDT datasheet, TSV792IYDT pinout, TSV792IYDT application, or TSV792IYDT equivalent, this device supports demanding analog front-ends requiring wide common-mode range (VCC− −0.1 V to VCC+ +0.1 V), low noise (6.5 nV/√Hz @ 10 kHz), and stable operation across −40 °C to +125 °C with 22 pF capacitive load drive capability.

Technical Context

The TSV792 employs a dual-input-stage architecture with complementary transistor pairs to enable true rail-to-rail input operation across its full common-mode range. Its unity-gain stability and 53° phase margin ensure robust closed-loop performance with up to 1 nF output capacitance.

It features two independent amplifiers sharing a single 8-pin MiniSO8 or DFN8 package, each with matched DC and AC characteristics: 50 MHz GBP, 30 V/µs slew rate, and <700 µV input offset over temperature - making it suitable for differential sensing and A/D buffer applications where channel-to-channel matching matters.

Key Specifications

Pinout & Package

TSV792IYDT is packaged in MiniSO8 (SO-8) - an industry-standard 8-pin surface-mount package with 1.27 mm pitch, rated for automotive-grade thermal performance (R_thJA = 127 °C/W).

FAQ

What is the maximum capacitive load the TSV792IYDT can drive while remaining stable?

The TSV792IYDT is fully specified and guaranteed stable with a 22 pF capacitive load and typically supports up to 1 nF without external compensation. Stability is verified per Figure 28 in DS13480 Rev 7, showing ≥53° phase margin at 10 kΩ load and 1 nF capacitance. For loads >100 pF, layout minimization of parasitic inductance and local decoupling are critical.

Does TSV792IYDT require external compensation for unity-gain operation?

No - the TSV792IYDT is internally compensated for unity-gain stability across its full supply (2.2–5.5 V) and temperature (−40 °C to +125 °C) ranges. Its 53° phase margin at unity gain is confirmed in Table 6 and Figure 23–26 of DS13480 Rev 7, eliminating need for external compensation networks in standard configurations.

How does the dual-input-stage architecture affect common-mode rejection near the supply rails?

The TSV792IYDT uses two complementary input pairs that transition near VCC+ −1.4 V. CMRR degrades slightly (to ~76 dB) when Vicm approaches VCC+ due to reduced active device bias - per Table 5 CMR2 spec. For best precision, keep Vicm ≤ VCC+ −2 V; Figure 12–13 confirm optimal CMRR in the lower 90% of the common-mode range.

Can unused amplifier channels in the TSV792IYDT be left floating?

No - unused channels must be configured to prevent oscillation and excess current draw. Per Section 5.4 of DS13480 Rev 7, either configure as unity-gain follower (IN+ tied to defined voltage within Vicm range) or as comparator (IN+ and IN− held ≥100 mV apart). Leaving inputs unconnected risks instability and increased ICC.
