Product details
Overview
TS954IYPT from STMicroelectronics is a quad rail-to-rail input/output BiCMOS operational amplifier optimized for 3 V and 5 V operation, delivering 3 MHz gain-bandwidth product, 1 V/µs slew rate, and 0.95 mA supply current per amplifier at 5 V. It operates from 2.7 V to 12 V, features ±100 nA input bias current, 80 dB supply voltage rejection ratio, and is qualified for automotive applications per AEC-Q100. It serves as a precision signal conditioner in battery-powered sensor front-ends.
For engineers reviewing the TS954IYPT datasheet, TS954IYPT pinout, TS954IYPT application, or TS954IYPT equivalent, this page delivers verified package mapping (TSSOP14), confirmed rail-to-rail I/O behavior, real-world THD (0.01% at 10 kHz), latch-up immunity (200 mA), and automotive-grade thermal performance (–40 °C to 125 °C).
Technical Context
The TS954IYPT implements a BiCMOS input stage enabling rail-to-rail common-mode input range (VDD − 0.2 V to VCC + 0.2 V) and rail-to-rail output swing (within 100 mV of rails at 600 Ω load). Its 3 MHz GBP and 1 V/µs slew rate support medium-speed closed-loop configurations including active filters and DAC buffers without phase margin degradation (60° at unity gain with 100 pF load).
Designed for low-voltage industrial and automotive systems, it maintains stable DC accuracy across temperature: input offset voltage drift is 2 µV/°C, and CMRR remains ≥50 dB over full operating range. ESD robustness includes 3 kV HBM and 1 kV CDM ratings, meeting stringent automotive board-level reliability requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS954IDT | SO14 package, non-automotive grade (–40 °C to 125 °C), same electrical specs | Lacks AEC-Q100 qualification; unsuitable for automotive ECU designs | Select when cost-sensitive industrial use requires SO14 footprint and no automotive qualification |
| LMV324DT | Lower GBP (1 MHz), higher input bias current (100 nA), no AEC-Q100 rating | Insufficient bandwidth for active filters above 100 kHz; higher offset drift impacts precision DC gain | Choose only for basic DC-coupled amplification where speed and accuracy are secondary to ultra-low cost |
Compared with TS954IDT, TS954IYPT adds automotive qualification and tighter process control for extended temperature stability; versus LMV324DT, it delivers 3× higher bandwidth, 3× lower THD, and guaranteed latch-up immunity-critical for reliable operation in safety-relevant signal chains.

FAQ
Is TS954IYPT pin-compatible with TS954IDT?
Yes, TS954IYPT and TS954IDT share identical TSSOP14 pinout and electrical specifications. The sole difference is automotive qualification: TS954IYPT undergoes AEC-Q100 stress testing and screening, while TS954IDT is rated for industrial temperature range only. Both use the same marking "954IY" and require identical PCB layout and decoupling.
What is the maximum capacitive load the TS954IYPT can drive without instability?
TS954IYPT maintains 60° phase margin with 100 pF capacitive load at unity gain (RL = 600 Ω), as verified in the datasheet's Figure 3 and Table 3. For loads exceeding 100 pF, a series isolation resistor (≥100 Ω) between output and capacitance is required to preserve stability-critical when driving ADC input capacitors or long PCB traces.
Does TS954IYPT support true single-supply operation with input signals at ground?
Yes. Its rail-to-rail input common-mode range extends to VDD − 0.2 V, allowing direct connection of 0 V-referenced sensors (e.g., thermistors, bridge transducers) in single-supply configurations. No external level-shifting circuitry is needed, reducing component count and board area in portable designs.
How does the 3 kV HBM ESD rating impact system-level robustness?
The 3 kV HBM rating (per Table 1) reflects validated on-chip protection diodes capable of safely clamping electrostatic discharges during handling and assembly. This exceeds standard IEC 61000-4-2 Level 2 (4 kV contact) requirements when combined with proper PCB layout-ensuring reliability in automotive manufacturing and field service environments.
