Product details
Overview
TSB514IPT from STMicroelectronics is a quad rail-to-rail input/output operational amplifier optimized for high-precision current sensing and industrial signal conditioning. It operates from 2.7 V to 36 V single supply (or ±1.35 V to ±18 V dual supply), delivers 6 MHz gain bandwidth, 3 V/µs slew rate, and 12 nV/√Hz input voltage noise-enabling accurate amplification of low-level transducer signals in motor control and process instrumentation.
For engineers reviewing the TSB514IPT datasheet, TSB514IPT pinout, TSB514IPT application, or TSB514IPT equivalent, key selection criteria include its guaranteed rail-to-rail operation across automotive-grade temperature range (−40 °C to +125 °C), integrated EMI filtering, 2 kV HBM ESD tolerance, and validated performance at 36 V supply with ≤2 µV/°C offset drift.
Technical Context
The TSB514IPT implements a fully differential, unity-gain-stable CMOS input stage with internal compensation, supporting stable operation into 100 pF capacitive loads. Its rail-to-rail input common-mode range extends from VCC− −0.2 V to VCC+ +0.2 V, and output swing reaches within 90 mV of either rail under 2 mA load at 5 V supply.
Designed for multi-channel precision analog front-ends, it features channel separation >100 dB at 10 kHz and cross-talk <−100 dB at 10 kHz (VCC = 36 V), enabling simultaneous high-fidelity amplification of four independent sensor signals without inter-channel interference.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6 MHz - supports closed-loop gain ≥10 at 600 kHz for anti-aliasing filter design in 1 MSPS ADC interfaces. |
| Slew Rate | 3 V/µs - enables faithful reproduction of 100 kHz full-scale sine waves with <0.1% distortion at 10 Vpp output. |
| Input Offset Voltage | ±1.5 mV max (25 °C) - ensures ≤0.015% error in 100 mV full-scale current-sense shunt measurements. |
| Input Voltage Noise | 12 nV/√Hz @ 10 kHz - critical for preserving SNR in Hall-effect sensor interfaces with 1–10 kHz bandwidth. |
| Supply Voltage Range | 2.7 V to 36 V single supply - eliminates need for level-shifting in 24 V industrial PLC I/O modules. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive motor drivers and factory-floor process controllers. |
| EMI Filtering | Integrated - reduces susceptibility to 30–1000 MHz RF interference in noisy industrial environments without external RC filters. |
Pinout & Package
TSSOP14 package: 4.9 mm × 6.4 mm body, 0.65 mm pitch, 1.05 mm height, JEDEC MO-153 compliant, RoHS-compliant ECOPACK2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT1–OUT4 | Amplified outputs; each drives ≥25 mA sink/source, rail-to-rail swing, low 90 mV saturation voltage. |
| 2, 6, 9, 13 | IN1−, IN2−, IN3−, IN4− | Inverting inputs; support common-mode range to VCC− −0.2 V, enabling high-side current sensing with ground-referenced shunts. |
| 3, 5, 10, 12 | IN1+, IN2+, IN3+, IN4+ | Non-inverting inputs; matched bias current (<200 nA) minimizes offset error in resistive bridge amplifiers. |
| 4 | VCC+ | Positive supply terminal; accepts up to +40 V absolute max, decoupling required within 1 cm for EMI immunity. |
| 11 | VCC− | Negative supply terminal; functions as ground reference in single-supply mode; supports true dual-supply operation. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input common-mode extends 0.2 V beyond rails; output swings to within 90 mV of VCC+/VCC− - enables direct interfacing to 3.3 V microcontrollers and 24 V sensors. |
| Low 1.5 mV offset | Max offset over full temperature range ensures ≤0.03% gain error in 4–20 mA transmitter circuits using 25 Ω shunts. |
| 6 MHz GBW + 3 V/µs SR | Supports closed-loop bandwidth >1 MHz at G = 5 - sufficient for real-time current loop control in servo drives. |
| Integrated EMI filter | Attenuates >30 dB RF energy above 100 MHz - eliminates need for external ferrite beads in EN 61000-4-3 compliant designs. |
| 2 kV HBM ESD | Withstands electrostatic discharge during PCB handling and field service - reduces failure rate in automated test equipment. |

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 |
|---|---|---|---|
| TSB714IPT | Higher precision: ±0.3 mV offset, 0.5 µV/°C drift, but lower 3.5 MHz GBW and 1.4 V/µs slew rate. | Better for static-accuracy-critical applications (e.g., precision weigh scales); unsuitable for >350 kHz closed-loop bandwidth needs. | Select TSB714IPT only when offset drift dominates system error budget and bandwidth demand is ≤300 kHz. |
| LM324DT | Lower cost, wider temp range (−40 °C to +105 °C), but no rail-to-rail I/O, 1.2 MHz GBW, 0.5 V/µs slew rate, higher 20 nV/√Hz noise. | Acceptable for non-critical 12-bit ADC interfaces where 36 V supply and EMI immunity are not required. | Choose LM324DT only for cost-sensitive, non-automotive applications with relaxed noise, speed, and rail compliance requirements. |
Compared with TSB714IPT, TSB514IPT trades offset precision for bandwidth and slew rate-making it superior for dynamic current sensing; versus LM324DT, it delivers 5× higher GBW, rail-to-rail operation, and integrated EMI filtering essential for industrial EMC compliance.

FAQ
Is TSB514IPT qualified for automotive applications?
Yes-TSB514IPT is AEC-Q100 qualified (Grade 1, −40 °C to +125 °C) and characterized per AEC-Q001/Q002 screening. Its 2 kV HBM ESD rating, integrated EMI filter, and guaranteed operation at 36 V supply meet requirements for engine control units, battery management systems, and electric power steering modules.
Can TSB514IPT drive capacitive loads up to 100 pF without oscillation?
Yes-the datasheet confirms stable unity-gain operation with 100 pF capacitive load (Table 6 and Figure 22). Phase margin remains ≥45° at 36 V supply, and overshoot stays below 15% (Figure 23), eliminating need for isolation resistors in typical sensor interface layouts.
What is the maximum output current per channel?
Each channel delivers ±25 mA continuous output current (sink/source) at 25 °C and 36 V supply (Table 7). At 125 °C, minimum guaranteed output current is ±20 mA-sufficient to drive 200 Ω loads at ±5 V output swing in motor gate driver bias networks.
Does TSB514IPT require external compensation components?
No-it is internally compensated for unity-gain stability across its full supply and temperature range. No external capacitors or resistors are needed for stable operation, simplifying PCB layout and reducing bill-of-materials cost in multi-channel analog front-ends.
