Product details
Overview
TSX564IPT from STMicroelectronics is a quad-channel, rail-to-rail input micropower CMOS operational amplifier optimized for high-impedance sensor interfaces and automotive signal conditioning. It delivers 900 kHz gain bandwidth, 250 µA supply current per channel at 16 V, 600 µV max offset voltage (A-grade), ±0.1 V rail-to-rail input range, and operates across –40 °C to +125 °C.
For engineers reviewing the TSX564IPT datasheet, TSX564IPT pinout, TSX564IPT application, or TSX564IPT equivalent, key selection criteria include micropower operation under 300 µA/channel, wide 3–16 V supply range, low 1 pA input bias current, high 4 kV HBM ESD tolerance, and TSSOP14 packaging for space-constrained industrial and automotive PCBs.
Technical Context
The TSX564IPT employs complementary PMOS/NMOS input stages enabling true rail-to-rail input operation from (VCC–) – 0.1 V to (VCC+) + 0.1 V, with performance optimized over the extended common-mode range of (VCC–) – 0.1 V to (VCC+) – 1.5 V. Its 900 kHz GBP and 1.1 V/µs slew rate support stable active filtering up to ~100 kHz.
It features low 55 nV/√Hz input voltage noise at 1 kHz, 15 µVPP 0.1–10 Hz peak-to-peak noise, and <0.0005% THD+N at 5 VPP, making it suitable for precision DC-coupled amplification and low-distortion AC signal paths in medical and instrumentation systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad micropower op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Lower GBP (600 kHz), higher IQ (550 µA/channel), no A-grade option; 2.7–6 V only. | Limited to low-voltage systems; insufficient for 12 V automotive sensor biasing. | Choose only if supply is strictly ≤6 V and 900 kHz bandwidth is not required. |
| LMV324IPWR | Higher IQ (120 µA/channel at 5 V but degrades above 5 V), no rail-to-rail input, 1 mV VIO max, 2 kV HBM. | Cannot interface directly with signals near VCC; unsuitable for high-accuracy DC-coupled sensor chains. | Select only for cost-sensitive, non-automotive, single-supply ≤5.5 V applications where rail-to-rail input is unnecessary. |
Compared with TLV2464IDR and LMV324IPWR, TSX564IPT uniquely combines 900 kHz bandwidth, 250 µA/channel at 16 V, rail-to-rail input, and automotive temperature/ESD ratings - making it the only qualified solution for high-precision, wide-supply, multi-channel sensor front-ends in harsh environments.

FAQ
Is TSX564IPT pin-compatible with other quad op-amps in TSSOP14?
TSX564IPT follows standard TSSOP14 quad op-amp pinout (dual-in-line functional mapping: Ch1–Ch4 inputs/outputs with shared VCC+/VCC–). It matches industry-standard pin assignments used by LM324, TLV2464, and MCP6004 families - enabling drop-in replacement where electrical specs align, though layout review for decoupling and thermal relief is recommended.
Does TSX564IPT support true rail-to-rail output swing?
No - TSX564IPT features rail-to-rail *input* only. Output swing is specified to within 70 mV of each rail (VOH/VOL) under 10 kΩ load. For rail-to-rail output, ST recommends the TSZ124 family; TSX564IPT's strength lies in input range and micropower, not output headroom.
What is the maximum capacitive load TSX564IPT can drive stably?
Per Figure 13 in the datasheet, TSX564IPT maintains ≥55° phase margin with up to 100 pF capacitive load at 12 V supply. Driving >100 pF requires isolation resistor (≥10 Ω) between output and capacitance to prevent peaking or oscillation - critical for anti-aliasing filter implementations.
How does the "A" suffix affect TSX564IPT performance?
The "A" in TSX564IPT denotes the enhanced offset grade: 600 µV max VIO at 25 °C (vs. 1 mV for standard TSX564). This tighter spec reduces initial DC error in precision gain stages and improves system accuracy over temperature - especially valuable in uncalibrated sensor modules where offset trimming is impractical.
