Product details
Overview
TSX564IYPT 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 product, 250 µA supply current per channel at 16 V, 600 µV max input offset voltage (A-grade), ±0.1 V beyond rails common-mode range, and operates across –40 °C to +125 °C.
For engineers reviewing the TSX564IYPT datasheet, TSX564IYPT pinout, TSX564IYPT application, or TSX564IYPT equivalent, this device is selected for precision, low-power industrial sensing, battery-powered instrumentation, and AEC-Q100-compliant automotive subsystems where ESD robustness (4 kV HBM) and wide supply range (3–16 V) are critical.
Technical Context
The TSX564IYPT 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 range (VCC–) – 0.1 V to (VCC+) – 1.5 V. Its 1 pA typical input bias current and 15 µVPP (0.1–10 Hz) low-frequency noise support direct interfacing with high-impedance sources like piezoresistive sensors and pH electrodes.
It features a stable 55° phase margin into 100 pF capacitive loads and maintains 750–900 kHz GBP across 3–16 V supply, with CMRR up to 95 dB and PSRR up to 90 dB - enabling accurate DC-coupled amplification in noisy automotive and industrial environments without external compensation.
Key Specifications

|---|---|
| Supply Voltage | 3 V to 16 V - supports direct connection to 5 V, 12 V, and 15 V industrial/automotive rails without regulation. |
| Gain Bandwidth Product | 900 kHz typ. at 16 V - enables stable unity-gain buffering of signals up to ~750 kHz with <5% gain error. |
| Input Offset Voltage | 600 µV max. (A-grade, 25 °C) - ensures ≤0.012% full-scale error in 5 V-span 12-bit systems without trimming. |

Applications
| Automotive Cabin Sensors | Industrial 4–20 mA Transmitters |
|---|---|
|

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 |
|---|---|---|---|
| TSX564AIDT | Same die, TSSOP14 package, but A-grade (600 µV max VIO) and tighter ΔVIO/ΔT (2–12 µV/°C). | Preferred for medical-grade DC accuracy where long-term drift must be minimized below 1 µV/°C. | Select TSX564AIDT when VIO spec is primary; TSX564IYPT offers identical performance at lower cost for industrial use. |
| LMV324QDRQ1 | Lower GBP (1 MHz), higher ICC (120 µA/ch), no A-grade option, 36 V max supply - not rail-to-rail input. | Suitable for 12 V automotive powertrain where wider supply range matters more than precision. | Choose LMV324QDRQ1 only if 36 V tolerance is required; TSX564IYPT outperforms in noise, offset, and input range for cabin/sensing apps. |
Compared with TSX564AIDT, TSX564IYPT trades minor VIO tolerance relaxation (1 mV vs. 600 µV) for broader availability and cost efficiency, while matching all key specs (bandwidth, bias current, ESD, temp range); versus LMV324QDRQ1, it delivers superior DC precision, lower noise, and true rail-to-rail input - critical for sensor front-ends.

FAQ
Is TSX564IYPT pin-compatible with other quad op-amps in TSSOP14?
Yes - TSX564IYPT follows the industry-standard TSSOP14 pinout for quad op-amps (e.g., LM324, TL084), with Channels 1–4 arranged sequentially. Pin 4 is VCC–, Pin 11 is VCC+, and all inputs/outputs align to JEDEC MO-153. No adapter or layout change is needed for drop-in replacement in existing designs meeting its voltage and bandwidth requirements.
Does TSX564IYPT support true rail-to-rail output?
No - TSX564IYPT features rail-to-rail *input* only. Its output swings to within 70 mV of each rail under 10 kΩ load (typical), as specified in Table 4–6. For full rail-to-rail output, ST recommends the TSZ124 or TSX924 families; TSX564IYPT prioritizes input range and micropower over output swing.
What decoupling is required for stable operation?
Per Section 5.5 of the datasheet, a 10 nF X7R ceramic capacitor must be placed as close as possible to both VCC+ (Pin 11) and VCC– (Pin 4), with short, low-inductance traces. Additional bulk capacitance (e.g., 1 µF) is recommended on the board-level supply rail, but the 10 nF local caps are mandatory to suppress high-frequency oscillation and ensure 55° phase margin stability.
Can TSX564IYPT drive capacitive loads directly?
Yes - it remains stable with up to 100 pF capacitive load at unity gain, as verified in Figure 13 (phase margin ≥55°). For loads >100 pF, a small isolation resistor (10–50 Ω) between output and cap is recommended. The device does not require external compensation networks, simplifying design for active filters and sensor cable driving.
