Product details
Overview
TSV914IYPT from STMicroelectronics is a quad rail-to-rail input/output operational amplifier optimized for low-voltage, low-power applications. It delivers 8 MHz gain-bandwidth, 4.5 V/µs slew rate, 1.1 mA max supply current per channel, and operates from 2.5 V to 5.5 V. Its 1 pA typical input bias current and 1.5 mV max input offset voltage (A grade) make it suitable for precision sensor interfaces in automotive-grade portable instrumentation.
For engineers reviewing the TSV914IYPT datasheet, TSV914IYPT pinout, TSV914IYPT application, or TSV914IYPT equivalent, key selection criteria include rail-to-rail I/O swing at 2.5 V supply, ±100 pA input bias current over temperature, 35 mA output drive capability, unity-gain stability with 100 pF capacitive load, and AEC-Q100 qualified automotive reliability.
Technical Context
The TSV914IYPT implements a CMOS input stage enabling ultra-low input bias current (1 pA typ.) and rail-to-rail common-mode input range (VCC− − 0.1 V to VCC+ + 0.1 V). Its fully differential output stage supports rail-to-rail swing into 600 Ω loads while maintaining 45° phase margin at unity gain.
It features internal ESD protection ≥5 kV HBM and latch-up immunity up to 200 mA. The device is specified across −40 °C to +125 °C and qualified to AEC-Q100 Grade 1, confirming suitability for under-hood automotive signal conditioning where supply voltage may dip to 2.3 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 8 MHz - enables stable closed-loop operation up to ~1 MHz with gain ≥8, supporting active filter and anti-aliasing designs. |
| Supply voltage range | 2.5 V to 5.5 V - compatible with single-cell Li-ion (3.0–3.7 V), 3.3 V logic rails, and automotive 5 V domains. |
| Input bias current | 1 pA typ. at 25 °C - minimizes voltage error in high-impedance sensor nodes (e.g., pH electrodes, photodiode transimpedance). |
| Input offset voltage | 1.5 mV max (A grade) - ensures <0.03% full-scale error in 5 V-span 12-bit ADC front-ends. |
| Slew rate | 4.5 V/µs - supports 10 kHz full-scale sine output at 20 Vpp without distortion in unity-gain buffer configurations. |
| Output drive | ±35 mA - drives 600 Ω loads to rail with <150 mV saturation, enabling direct interface to analog switches or LED bias circuits. |
| ESD rating | ≥5 kV HBM - meets IEC 61000-4-2 Level 4 system-level robustness requirements for automotive infotainment and body control modules. |
Pinout & Package
TSV914IYPT is housed in a 14-lead TSSOP package (JEDEC MO-153, 5.0 mm × 4.4 mm × 1.2 mm), qualified for automotive use and featuring exposed pad (not internally connected, may be tied to VCC− or left floating).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Channel 1 output | Capable of sourcing/sinking ±35 mA; rail-to-rail swing with <150 mV headroom at 600 Ω load. |
| 2 (IN1−) | Channel 1 inverting input | CMOS input node; 1 pA bias current enables high-Z feedback networks without drift. |
| 3 (IN1+) | Channel 1 non-inverting input | Common-mode range extends 0.1 V beyond rails-supports direct sensing of battery voltage or thermistor dividers. |
| 4 (VCC+) | Positive supply | Accepts 2.5–5.5 V; decoupling capacitor required within 2 mm for stability with >100 pF capacitive loads. |
| 5 (VCC−) | Negative supply / ground reference | Reference for all inputs/outputs; exposed pad may be connected here to improve thermal resistance (RthJA = 100 °C/W). |
| 6 (OUT2) | Channel 2 output | Electrically identical to OUT1; independent channel allows dual-sensor buffering or differential driver stages. |
| 7 (IN2−) | Channel 2 inverting input | Matched to IN1−; enables precise dual-channel instrumentation amplifier topologies. |
| 8 (IN2+) | Channel 2 non-inverting input | Same rail-to-rail CM range as IN1+; supports synchronous multi-channel acquisition. |
| 9 (OUT3) | Channel 3 output | Full performance replication; enables 3-phase motor current sensing or triple-redundant safety monitoring. |
| 10 (IN3−) | Channel 3 inverting input | Low input capacitance (<3 pF) preserves bandwidth in high-frequency transimpedance configurations. |
| 11 (IN3+) | Channel 3 non-inverting input | Enables single-supply level-shifting of AC-coupled signals without external bias resistors. |
| 12 (IN4+) | Channel 4 non-inverting input | Supports parallel-input architectures such as programmable-gain amplifiers with shared gain-setting resistors. |
| 13 (IN4−) | Channel 4 inverting input | Allows implementation of unity-gain inverting buffers with matched input impedance to IN4+. |
| 14 (OUT4) | Channel 4 output | Delivers same 4.5 V/µs slew rate and 8 MHz GBW as other channels-critical for time-aligned multi-channel signal chains. |
Key Features

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 |
|---|---|---|---|
| TSV914IDT | Industrial grade (−40 °C to +125 °C), same electrical specs but not AEC-Q100 qualified; SO-14 package (larger footprint, higher RthJA = 103 °C/W). | Lacks automotive qualification; unsuitable for under-hood or safety-critical modules requiring AEC-Q100 documentation. | Select when cost-sensitive industrial automation requires quad op amps without automotive certification. |
| TSV994IPT | Higher speed: 20 MHz GBW, 10 V/µs slew rate; 1.4 mA/channel supply current; same AEC-Q100 Grade 1 rating and TSSOP-14 package. | Better suited for wideband applications like ultrasonic sensing or active EMI filtering where >8 MHz bandwidth is required. | Choose when system-level bandwidth exceeds 1 MHz and additional power budget permits 70% higher quiescent current. |
Compared with TSV914IDT, TSV914IYPT adds AEC-Q100 compliance and tighter Vos distribution for automotive reliability, while TSV994IPT trades lower power for higher bandwidth-making TSV914IYPT optimal for precision, low-power automotive signal chains below 1 MHz.

FAQ
What is the maximum capacitive load the TSV914IYPT can drive without external compensation?
The TSV914IYPT is unity-gain stable and characterized to drive up to 100 pF capacitive loads directly at its output without oscillation, as verified in the datasheet's Figure 10 and Section 5.1. For loads exceeding 100 pF, a series resistor (typically 10–100 Ω) between the output and load is recommended to maintain phase margin above 45°.
Does the exposed pad on the TSSOP-14 package require a specific PCB connection?
No. The exposed pad on the TSV914IYPT's TSSOP-14 package is not internally connected to any die node. Per datasheet Section 6.5 and Figure 26, it may be left electrically floating or soldered to the VCC− (ground) plane to improve thermal performance-RthJA drops from 100 °C/W to ~85 °C/W when thermally coupled to a 200 mm² copper pour.
How does the input offset voltage specification differ between TSV914IYPT and TSV914IDT?
The TSV914IYPT (automotive A grade) specifies 1.5 mV maximum input offset voltage at 25 °C and 3 mV maximum over −40 °C to +125 °C, whereas the industrial TSV914IDT has 4.5 mV max at 25 °C and 7.5 mV max over temperature. This tighter Vos spec supports higher-accuracy automotive sensor calibration without trimming.
Can TSV914IYPT operate reliably at 2.3 V supply as stated in Table 2?
Yes. Table 2 specifies 2.3 V minimum supply for 0 °C to +125 °C operation. At 2.3 V, the device maintains rail-to-rail input range (VCC− − 0.1 V to VCC+ + 0.1 V), 7 MHz minimum GBW, and 30 mA minimum output drive-validated per AEC-Q100 stress testing for automotive cold-crank scenarios.
