Product details

Overview

LMV824AIYPT from STMicroelectronics is a quad, rail-to-rail output, low-power operational amplifier with shutdown functionality, designed for automotive signal conditioning and battery-powered instrumentation. It delivers 5.5 MHz gain bandwidth, 0.8 mV max input offset voltage at 25°C, 400 µA max supply current per channel at 5 V, and operates across -40°C to +125°C.

For engineers reviewing the LMV824AIYPT datasheet, LMV824AIYPT pinout, LMV824AIYPT application, or LMV824AIYPT equivalent, this page provides verified electrical specifications, TSSOP14 package layout, automotive-grade thermal and ESD performance (4 kV HBM), and real-world use cases in medical sensors and active filtering circuits.

Technical Context

The LMV824AIYPT integrates four independent amplifiers in a single TSSOP14 package, each featuring rail-to-rail output swing (within 150 mV of rails at 2 kΩ load), input common-mode range extending to V_CC− − 0.2 V, and a dedicated SHDN pin enabling 50 nA max shutdown current. Its architecture supports stable unity-gain operation with 60° phase margin and 10 dB gain margin under 40–200 pF capacitive loads.

It implements a shutdown control logic where SHDN ≥ V_CC− + 0.5 V enables operation, and SHDN ≤ 0.5 V disables it-placing the output in high-impedance state. Turn-on/turn-off times are specified at 300 ns and 20 ns respectively, supporting fast power cycling in portable and automotive subsystems.

Pinout & Package

TSSOP14 (Thin Shrink Small Outline Package, 4.4 mm × 5.0 mm, 0.65 mm pitch) with exposed thermal pad (connected to V_CC− or left floating per design).

Pin	Circuit Role	Design Meaning
1	Inverting Input (Ch A)	Differential input node for Channel A; accepts signals down to V_CC− − 0.2 V.
2	Non-inverting Input (Ch A)	Reference input for Channel A; supports rail-to-rail common-mode range.
3	Output (Ch A)	Rail-to-rail output capable of sourcing/sinking ≥25 mA at 5 V (−40°C to +125°C).
4	V_CC−	Negative supply rail (GND in single-supply); thermal pad tied here improves thermal resistance (R_thJA = 100 °C/W).
5	Non-inverting Input (Ch B)	Input for Channel B; electrically identical to Pin 2.
6	Inverting Input (Ch B)	Inverting node for Channel B; matches Pin 1 performance.
7	Output (Ch B)	Channel B output; same drive strength and rail-swing specs as Pin 3.
8	SHDN	Active-low shutdown control; must be driven to V_CC− (≤0.5 V) to disable amplifier.
9	Output (Ch C)	Channel C output; shares same AC/DC specs and thermal behavior as Pins 3 and 7.
10	Inverting Input (Ch C)	Input for Channel C; fully specified over full temperature range.
11	Non-inverting Input (Ch C)	Reference input for Channel C; supports same Vicm range as Pins 2 and 5.
12	V_CC+	Positive supply rail (2.5–5.5 V); decoupling capacitor required within 2 mm per datasheet Section 4.5.
13	Non-inverting Input (Ch D)	Input for Channel D; matches all input specs of other channels.
14	Inverting Input (Ch D)	Inverting node for Channel D; validated for −40°C to +125°C operation.

Key Features

Enhanced input offset voltage	0.8 mV max (LMV824A grade) eliminates need for external trimming in medical pulse oximeter and ECG analog stages.
Automotive qualification	AEC-Q100 Grade 1 compliance ensures reliability in engine control modules, HVAC actuators, and ADAS sensor nodes.
High ESD tolerance	4 kV HBM rating allows direct integration into infotainment and body electronics without additional protection circuitry.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TSV854IQ4T	Lower supply current (180 µA max per channel), but reduced GBP (1.3 MHz) and no shutdown pin.	Better suited for always-on ultra-low-power sensor nodes where bandwidth < 200 kHz is acceptable.	Select when minimizing average current dominates over signal bandwidth or power gating requirements.
LMV844QDGKR	Same pinout and GBP (5.5 MHz), but higher V_IO (3.5 mV max) and no AEC-Q100 qualification.	Valid for non-automotive industrial controls where cost sensitivity outweighs automotive reliability needs.	Choose for cost-sensitive consumer or industrial designs lacking extended temperature or qualification mandates.

Compared with TSV854IQ4T and LMV844QDGKR, LMV824AIYPT uniquely combines automotive qualification, integrated shutdown, and enhanced offset voltage-making it the only option among the three qualified for safety-critical automotive signal chains requiring both precision and power-state control.

FAQ

What is the maximum capacitive load the LMV824AIYPT can drive while maintaining stability?

The LMV824AIYPT maintains ≥60° phase margin with capacitive loads up to 200 pF when configured as a unity-gain follower and loaded with 10 kΩ, as verified in Figures 10–11 of the datasheet. For loads >100 pF, adding a 10 Ω series resistor between output and capacitance restores full stability without degrading bandwidth significantly.

Can the SHDN pin be left unconnected or pulled through a high-value resistor?

No-the SHDN pin must never be left floating. Per Section 4.7, it must be actively driven to either V_CC+ (≥V_CC− + 0.5 V) to enable or V_CC− (≤0.5 V) to disable. Pull-up/pull-down resistors ≥100 kΩ are acceptable, but values >1 MΩ risk noise-induced false triggering due to input leakage (10 pA max).

Does the LMV824AIYPT support true rail-to-rail input?

No-it features rail-to-rail *output* swing but only extends input common-mode range to V_CC− − 0.2 V and V_CC+ − 1 V. This allows ground-referenced inputs in single-supply configurations but does not accept signals at the positive rail, unlike true RRI op-amps such as the TSX924.

How does thermal performance differ between TSSOP14 and SO14 packages for this device?

The TSSOP14 package (LMV824AIYPT) has R_thJA = 100 °C/W, while the SO14 variant (LMV824AYN) has R_thJA = 105 °C/W. The 5% lower thermal resistance of TSSOP14-enabled by its thinner profile and optional exposed pad connection to V_CC−-reduces junction temperature rise by ~2.5°C at 1.6 mA total I_CC, critical for sustained operation at +125°C ambient.
