STMicroelectronics TSV6395IPT

Overview

TSV6395IPT from STMicroelectronics is a quad micropower rail-to-rail input/output operational amplifier in TSSOP-16 package, designed for low-voltage sensor signal conditioning and battery-powered instrumentation. It delivers 2.4 MHz gain bandwidth at 60 µA supply current per amplifier, supports 1.5 V to 5.5 V operation, features 5 nA shutdown current, and operates across –40 °C to 125 °C.

For engineers reviewing the TSV6395IPT datasheet, TSV6395IPT pinout, TSV6395IPT application, or TSV6395IPT equivalent, key selection considerations include its shutdown-enabled quad architecture, EMI-hardened performance (EMIRR up to 92 dB at 1.8 GHz), rail-to-rail I/O swing within 35 mV of rails, and guaranteed stability at gain ≥ –3 or ≥ 4 in inverting/non-inverting configurations.

Technical Context

The TSV6395IPT integrates four independent CMOS op-amps with complementary PMOS/NMOS input stages enabling true rail-to-rail input (–0.1 V to V_CC + 0.1 V) and output swing (≤35 mV from rails into 10 kΩ). Its internal trimming achieves ±17% spread on 60 µA typical supply current, directly stabilizing GBP (2.4 MHz), slew rate (1.1 V/µs), and open-loop gain (≥98 dB).

It implements a dedicated SHDN pin per amplifier block (pins 3, 6, 9, 12) that places outputs in high-impedance state with 5 nA total shutdown current at 5 V. The device is not unity-gain stable and requires minimum closed-loop gain of –3 (inverting) or 4 (non-inverting) for phase margin ≥60° with 100 pF load.

FAQ

What is the minimum recommended gain for stable operation of TSV6395IPT?

The TSV6395IPT requires minimum closed-loop gain of –3 in inverting configuration or +4 in non-inverting configuration to ensure ≥60° phase margin with 100 pF capacitive load. This is due to its internally compensated architecture optimized for 2.4 MHz GBP at 60 µA. Using gain < –3 or < +4 risks oscillation, especially with PCB trace capacitance exceeding 20 pF.

How does the shutdown function behave across temperature?

In shutdown mode, TSV6395IPT draws 5 nA typical at 25 °C, rising to 1.5 µA maximum at 125 °C. The SHDN pin threshold remains stable: VIH ≥ 2.0 V and VIL ≤ 0.8 V across –40 °C to 125 °C. Output impedance exceeds 1 GΩ in shutdown, verified per Table 4 and 7 of DS6635 Rev 4.

Can TSV6395IPT drive capacitive loads directly?

TSV6395IPT is characterized for stability with ≤100 pF capacitive load when gain ≥ –3 or ≥ 4. Driving >100 pF directly causes peaking or oscillation; for larger loads (e.g., ADC input capacitance), use an isolation resistor (≥220 Ω) between output and capacitor, or select unity-gain-stable alternatives like TSV63x series as noted in Section 5.6 of the datasheet.

What layout practices prevent EMI-induced errors?

To maintain specified 92 dB EMIRR at 1.8 GHz, place 10 nF X7R ceramic decoupling capacitors ≤2 mm from each V_CC pin, use solid ground plane beneath the TSSOP-16 footprint, route sensitive analog traces away from digital switching nodes, and avoid routing SHDN or output traces parallel to RF antennas. These practices are validated in ST's AN4899 layout guidelines.
