Product details

Overview

TSV524IYPT from STMicroelectronics is a quad rail-to-rail input/output operational amplifier optimized for ultra-low-power, high-precision signal conditioning in automotive and portable systems. It delivers 1.15 MHz gain bandwidth at 45 μA per channel (5 V), 800 μV max offset voltage, 1 pA typical input bias current, and operates from 2.7–5.5 V supply - enabling direct interfacing with high-impedance sensors in battery-powered ECUs.

For engineers reviewing the TSV524IYPT datasheet, TSV524IYPT pinout, TSV524IYPT application, or TSV524IYPT equivalent, key selection criteria include its AEC-Q100 qualification, rail-to-rail operation across –40 °C to +125 °C, low-noise (57 nV/√Hz @ 1 kHz), unity-gain stability with 100 pF load, and QFN16 3×3 mm package compatibility with space-constrained automotive modules.

Technical Context

The TSV524IYPT employs a complementary PMOS/NMOS input stage enabling true rail-to-rail input common-mode range (V_CC– – 0.1 V to V_CC+ + 0.1 V) without phase reversal. Its architecture maintains stable CMRR (76 dB typ. @ 5 V) and PSRR (87 dB typ.) across temperature and supply voltage variations.

It achieves unity-gain stability with capacitive loads up to 100 pF via internal compensation, supported by 55° phase margin and 7 dB gain margin. The device's 0.89 V/μs slew rate and 0.002% THD+N @ 1 kHz ensure fidelity in active filtering and sensor buffering applications requiring low distortion and fast settling.

Key Specifications

Parameter	Value and Actual Design Meaning
Gain Bandwidth Product	1.15 MHz @ 5 V - enables stable closed-loop gain ≥10 at 100 kHz for anti-aliasing filters
Supply Current per Channel	45 μA @ 5 V - extends battery life >10 years in always-on automotive sensors (e.g., tire pressure monitors)
Input Offset Voltage	800 μV max @ 25 °C - ensures ≤0.8 mV error in 1 V full-scale medical front-ends
Input Bias Current	1 pA typ. - preserves signal integrity when amplifying outputs from pH or piezoelectric sensors
Common-Mode Range	V_CC– – 0.1 V to V_CC+ + 0.1 V - allows direct sensing of signals near supply rails in single-supply data loggers
Output Swing	Within 35 mV of rails @ 10 kΩ - supports full dynamic range utilization in 3.3 V ADC interfaces
Operating Temperature	–40 °C to +125 °C - qualified for under-hood automotive control units per AEC-Q100 Grade 1

Pinout & Package

TSV524IYPT is housed in a thermally enhanced QFN16 3×3 mm package with exposed thermal pad (connected to V_CC– or left floating). Pin numbering follows standard top-view layout with 4 independent op-amp sections.

Pin/Terminal	Circuit Role	Design Meaning
1, 3, 5, 7	Inverting Input (IN1–, IN2–, IN3–, IN4–)	Differential inputs accepting signals down to V_CC– – 0.1 V; 1 pA bias current minimizes loading on high-Z sources
2, 4, 6, 8	Non-inverting Input (IN1+, IN2+, IN3+, IN4+)	Rail-to-rail common-mode range enables direct connection to resistive divider networks without level-shifting
9, 10, 11, 13	Output (OUT1, OUT2, OUT3, OUT4)	Capable of sourcing/sinking 36 mA @ 5 V; rail-to-rail swing reduces need for external level translators
12, 14, 15, 16	V_CC+ (Power)	Accepts 2.7–5.5 V; decoupling capacitor required within 1 mm for EMI suppression in automotive environments
NC (Pin 12)	No Connect	Unused terminal; must remain unconnected to avoid parasitic coupling in high-frequency layouts

Key Features

Feature	Design Value
Rail-to-rail I/O	Enables single-supply operation with full signal swing - eliminates dual-rail complexity in portable ECG monitors
AEC-Q100 Grade 1	Qualified for automotive ambient temperatures up to +125 °C - suitable for engine control, ADAS camera power domains
Unity-gain stable	Operates reliably with 100 pF capacitive loads - simplifies design of anti-aliasing filters without external compensation
Low input bias current	1 pA typ. - prevents DC error accumulation in high-impedance photodiode transimpedance amplifiers
High PSRR (87 dB)	Maintains accuracy in noisy 12 V automotive systems - rejects ripple from switching regulators feeding adjacent MCU domains

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
TSV524IPT	TSSOP14 package (larger footprint, higher R_thJA = 100 °C/W vs. QFN16's 45 °C/W)	Suitable for prototyping or non-automotive industrial use where thermal performance is less critical	Select for manual soldering or legacy board designs requiring through-hole-compatible footprint
LMV824DT	Higher GBP (5.5 MHz) but 220 μA/channel supply current; not AEC-Q100 qualified	Applicable in cost-sensitive consumer electronics, not automotive or medical-grade systems	Choose only for non-safety-critical applications needing higher speed at expense of power and qualification

Compared with TSV524IYPT, the TSV524IPT offers identical electrical specs but inferior thermal performance and larger size, while the LMV824DT trades AEC-Q100 compliance and ultra-low power for higher bandwidth - making TSV524IYPT the sole choice for space-constrained, thermally demanding automotive signal chains.

FAQ

Is TSV524IYPT pin-compatible with other quad op-amps in QFN16 packages?

No - TSV524IYPT uses a proprietary pinout optimized for its rail-to-rail architecture and thermal pad configuration. It is not pin-compatible with generic QFN16 op-amps like MCP6004 or TLV2464. Layout must follow ST's DS8862-recommended land pattern, including thermal pad solder stencil design and 0.3 mm pitch routing.

What is the maximum capacitive load the TSV524IYPT can drive without external compensation?

The TSV524IYPT is unity-gain stable with up to 100 pF capacitive load at the output, as verified in DS8862 Figure 29. For loads exceeding 100 pF, a series resistor (e.g., 10–100 Ω) must be added between the output and load to maintain phase margin >55°, especially in automotive environments with wide temperature swings.

Does the exposed thermal pad on the QFN16 package require electrical connection?

The exposed thermal pad may be connected to V_CC– (ground) or left electrically floating, per DS8862 note. However, thermal performance improves significantly when soldered to a dedicated ground plane - reducing junction-to-ambient thermal resistance from 45 °C/W to <30 °C/W in production PCBs with 2 oz copper and thermal vias.

How does the TSV524IYPT's input offset voltage drift compare across temperature?

ΔV_io/ΔT is guaranteed 3–18 μV/°C over –40 °C to +125 °C. At 125 °C, total offset remains ≤2.4 mV (vs. 800 μV at 25 °C), validated per AEC-Q100 stress testing. This drift is lower than standard precision op-amps (e.g., 25 μV/°C for OP177), ensuring stable calibration in under-hood temperature gradients.
