STMicroelectronics TSV914AID

Overview

TSV914AID from STMicroelectronics is a quad rail-to-rail input/output operational amplifier optimized for low-voltage, low-power applications. It delivers 8 MHz gain-bandwidth, 4.5 V/μs slew rate, and 1.1 mA max supply current per channel at 5 V, with rail-to-rail swing enabling full dynamic range in 2.5–5.5 V systems. It is used in precision sensor signal conditioning within portable medical instrumentation.

For engineers reviewing the TSV914AID datasheet, TSV914AID pinout, TSV914AID application, or TSV914AID equivalent, key selection criteria include its 1.5 mV max input offset voltage (A grade), 1 pA typical input bias current, 35 mA output drive capability, and stability with capacitive loads up to 100 pF in unity-gain follower configurations.

Technical Context

The TSV914AID implements a CMOS input stage with ultra-low input bias current (1 pA typ.) and rail-to-rail input common-mode range extending 0.1 V beyond rails. Its internal compensation ensures unity-gain stability without external components across 2.5–5.5 V supply operation.

It features a high-output-current architecture delivering ±35 mA into resistive loads, with output swing within 40 mV of rails at 10 kΩ load. Phase margin remains ≥45° with 100 pF capacitive load and 2 kΩ series resistance, supporting robust active filtering and sensor interface designs.

Key Specifications

Pinout & Package

Equivalent & Alternatives

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

Compared with TSV914AID, TSV994AIDT trades 2 MHz extra bandwidth and higher output drive for +0.3 mA/ch power penalty, while LMV324QDRQ1 sacrifices speed and offset accuracy to achieve 1/9th quiescent current and AEC-Q100 compliance-making each optimal for distinct power-performance-safety trade-offs.

FAQ

What is the maximum capacitive load the TSV914AID can drive without external compensation?

The TSV914AID is unity-gain stable and can drive up to 100 pF capacitive load directly in voltage-follower configuration without oscillation, as verified by phase margin ≥45° at 5 V supply. For loads exceeding 100 pF, a series resistor (10–100 Ω) between output and capacitance restores stability; exact value depends on load magnitude and must be validated via bench testing per Section 5.1 of DS4899.

Does the exposed pad on the SO-14 package require connection?

No-the exposed pad on the TSV914AID SO-14 package is not internally connected and may be left floating or tied to VCC− (GND) for improved thermal conduction and mechanical anchoring. STMicroelectronics' recommended footprint (Figure 28, DS4899 Rev 13) shows it as unconnected; grounding it does not affect electrical performance but enhances PCB heat dissipation during sustained 35 mA output operation.

How does the TSV914AID's input offset voltage drift behave over temperature?

The TSV914AID exhibits ∆V_os/∆T = 5 µV/°C maximum, meaning its input offset voltage increases by no more than 5 µV per degree Celsius change from 25 °C. Over the full −40 °C to +125 °C range, this contributes ≤825 µV additional drift beyond the 1.5 mV room-temperature maximum, resulting in worst-case V_os ≤2.325 mV-still sufficient for 12-bit precision in 5 V full-scale systems.

Can the TSV914AID operate from a single 2.5 V supply with rail-to-rail input and output?

Yes-the TSV914AID is fully specified for 2.5 V single-supply operation: input common-mode range extends from (VCC−) − 0.1 V to (VCC+) + 0.1 V, and output swings within 40 mV of both rails under 10 kΩ load. At 2.5 V, it delivers 8 MHz GBP and 4.5 V/μs slew rate, enabling accurate amplification of signals near ground or near VCC without level-shifting circuitry.
