STMicroelectronics TSB711AIYLT

Overview

TSB711AIYLT from STMicroelectronics is a precision rail-to-rail input/output operational amplifier optimized for high-side and low-side current sensing, Hall effect sensor signal conditioning, and industrial instrumentation. It delivers 6 MHz gain bandwidth, 3 V/µs slew rate, 300 µV max input offset voltage at 25 °C, and operates from 2.7 V to 36 V single supply. Its integrated EMI filter and 2 kV HBM ESD rating support robust operation in motor control and automotive-grade systems.

For engineers reviewing the TSB711AIYLT datasheet, TSB711AIYLT pinout, TSB711AIYLT application, or TSB711AIYLT equivalent, key selection criteria include its guaranteed rail-to-rail I/O performance across -40 °C to +125 °C, low 12 nV/√Hz input voltage noise at 10 kHz, 115 dB CMRR over extended common-mode range, and SOT23-5 package compatibility with space-constrained PCB layouts.

Technical Context

The TSB711AIYLT employs a complementary NPN/PNP input stage enabling true rail-to-rail input operation from VCC− to (VCC+)+0.1 V, with optimal DC performance maintained from VCC− to (VCC+)−1.5 V. Its internal EMI filter suppresses RF rectification effects, directly improving offset stability in noisy industrial environments.

It features a unity-gain-stable architecture with 45° phase margin at 36 V, supports capacitive loads up to 100 pF, and maintains 105–125 dB open-loop gain across −40 °C to +125 °C - critical for precision closed-loop current sensing where gain drift impacts measurement accuracy.

FAQ

What is the maximum capacitive load the TSB711AIYLT can drive stably?

The TSB711AIYLT is characterized for stable operation with up to 100 pF capacitive load at unity gain, per Figure 26 in DS12487 Rev 7. Driving larger loads requires external isolation resistance (≥10 Ω) or gain ≥2 to maintain ≥45° phase margin. Stability is verified at both 5 V and 36 V supplies across −40 °C to +125 °C.

Does the TSB711AIYLT support true rail-to-rail input beyond the supply rails?

Yes - its input common-mode range extends from VCC− to (VCC+)+0.1 V, allowing inputs to exceed the positive rail by 100 mV. However, optimal DC performance (CMRR, offset) is specified only up to (VCC+)−1.5 V. Operation above that point may degrade CMRR due to PNP/NPN input stage transition, as documented in Figures 11–12.

How does the integrated EMI filter function in the TSB711AIYLT?

The EMI filter is a monolithic RC network embedded at the input pins, attenuating RF signals (notably 400–2.5 GHz) before they reach the input differential pair. This prevents RF rectification that would otherwise shift input offset voltage - demonstrated by >20 dB improvement in EMIRR vs. non-filtered equivalents like TSB511, per ST application note AN5025.

Is the TSB711AIYLT pin-compatible with other devices in the TSB71x family?

TSB711AIYLT (SOT23-5) shares identical pinout with TSB711 and TSB711A variants, but is not pin-compatible with dual-channel TSB712/TSB712A (MiniSO8/SO8). The SOT23-5 layout matches industry-standard footprints, enabling drop-in replacement for TLV27x, MCP60x, or AD86xx-series op amps with same 5-pin configuration.
