STMicroelectronics TSV914AIDT

Overview

TSV914AIDT 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 1.5 mV max input offset voltage (A grade) while consuming only 1.1 mA per channel at 5 V. Its 2.5–5.5 V supply range, 1 pA typical input bias current, and ±5 kV ESD protection make it suitable for precision sensor interfaces in portable medical instrumentation.

For engineers reviewing the TSV914AIDT datasheet, TSV914AIDT pinout, TSV914AIDT application, or TSV914AIDT equivalent, key selection criteria include rail-to-rail output swing into 600 Ω loads, unity-gain stability with 100 pF capacitive load, low THD+noise (0.0004% at 1 kHz), and guaranteed operation across –40 °C to +125 °C ambient temperature.

Technical Context

The TSV914AIDT implements a CMOS input stage enabling ultra-low 1 pA input bias current and rail-to-rail common-mode input range (VCC− − 0.1 V to VCC+ + 0.1 V). Its internal compensation ensures unity-gain stability without external components, supporting direct use in follower, active filter, and transimpedance configurations.

It features a high-output-current architecture delivering ±35 mA into resistive loads and maintains phase margin ≥45° with 100 pF capacitive load. The device's 8 MHz GBP and 4.5 V/µs slew rate are specified across full supply (2.5–5.5 V) and temperature (–40 to +125 °C) ranges, with input offset drift limited to 5 µV/°C.

Key Specifications

Pinout & Package

TSV914AIDT is packaged in SO-14 (Small Outline 14-pin), a surface-mount plastic package with 1.27 mm pitch, 8.65 mm × 6.00 mm body size, and exposed thermal pad not internally connected (may be tied to VCC− or left floating).

FAQ

What is the maximum capacitive load the TSV914AIDT can drive without external compensation?

The TSV914AIDT is unity-gain stable and can drive up to 100 pF capacitive load directly in voltage-follower configuration without oscillation, as verified in Figure 10 and Section 5.1 of DS4899. For loads exceeding 100 pF, a series resistor (10–100 Ω) between output and load is required to maintain phase margin ≥45°.

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

No-the exposed pad on the TSV914AIDT's SO-14 package is not internally connected to any die node. Per Section 6.6 and Figure 28 of DS4899, it may be soldered to VCC− for improved thermal performance or left floating; neither choice affects electrical functionality, but thermal resistance drops from 103 °C/W to ~85 °C/W when tied to VCC−.

How does the TSV914AIDT perform at 2.5 V supply compared to 5 V?

At 2.5 V, the TSV914AIDT maintains full 8 MHz GBP, 4.5 V/µs slew rate, and 1.5 mV max Vio (A grade), with supply current dropping to 0.78 mA per channel. Common-mode range extends from VCC− − 0.1 V to VCC+ + 0.1 V, enabling true rail-to-rail operation even at minimum supply-critical for coin-cell and energy-harvesting systems.

Is the TSV914AIDT qualified for automotive applications?

The TSV914AIDT itself is not AEC-Q100 qualified; however, the automotive-grade variants TSV914AIYDT and TSV914AIYPT (listed in Table 12) are fully qualified to AEC-Q100 Grade 1 (–40 °C to +125 °C) with advanced screening per AEC-Q001/Q002. These share identical electrical specs but include extended reliability testing and traceable lot documentation.
