Product details

Overview

LMV824IPT from STMicroelectronics is a quad, rail-to-rail output, low-power operational amplifier with automotive qualification (AEC-Q100 Grade 1), 5.5 MHz gain bandwidth product, 400 µA max supply current per channel at 5 V, and 0.8 mV max input offset voltage at 25°C - used for precision signal conditioning in battery-powered automotive sensor interfaces.

For engineers reviewing the LMV824IPT datasheet, LMV824IPT pinout, LMV824IPT application, or LMV824IPT equivalent, key selection criteria include shutdown capability (50 nA max ICC in shutdown), extended temperature operation (-40°C to +125°C), rail-to-rail output swing under 2 kΩ load, and TSSOP14 package compatibility with high-density PCB layouts.

Technical Context

The LMV824IPT implements a CMOS input stage with rail-to-rail output stage, enabling full-swing operation from 2.5 V to 5.5 V supplies. Its 5.5 MHz GBP and 1.4–1.9 V/µs slew rate support stable unity-gain buffer and active filter configurations up to ~100 kHz.

It features an integrated shutdown control (SHDN pin) that places all four amplifiers into high-impedance output state with 50 nA max total supply current. Input common-mode range extends from V_CC− − 0.2 V to V_CC+ − 1 V, supporting ground-referenced sensing without phase reversal.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	2.5 V to 5.5 V - supports single-cell Li-ion and dual-cell alkaline battery systems without LDO pre-regulation.
Gain Bandwidth Product	5.5 MHz - enables stable closed-loop gain ≥10 up to ~500 kHz with adequate phase margin (>60°).
Input Offset Voltage	0.8 mV max at 25°C (LMV824A variant) - reduces DC error in 12-bit ADC front-ends without trimming.
Supply Current per Channel	400 µA max at 5 V - allows four-channel operation at <1.6 mA total, critical for multi-sensor nodes.
Shutdown Current	50 nA max at 25°C - enables microamp-level system sleep mode while retaining fast wake-up (<300 ns turn-on).
Rail-to-Rail Output Swing	±150 mV from rails into 2 kΩ load - preserves dynamic range in low-voltage data acquisition systems.
Operating Temperature	-40°C to +125°C - qualified for engine bay, transmission, and ADAS sensor modules per AEC-Q100 Grade 1.

Pinout & Package

TSSOP14 package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, exposed pad (optional thermal connection to V_CC− or floating), JEDEC MO-153 compliant.

Pin/Terminal	Circuit Role	Design Meaning
1 (OUT A)	Amplifier A output	Rail-to-rail output capable of sourcing/sinking ≥25 mA at 5 V; high-Z in shutdown.
2 (IN− A)	Amplifier A inverting input	CMOS input with 60–120 nA bias current; supports input down to V_CC− − 0.2 V.
3 (IN+ A)	Amplifier A non-inverting input	Same CMOS input characteristics as IN− A; no phase reversal across full common-mode range.
4 (V_CC−)	Negative supply rail	Ground reference for single-supply operation; SHDN logic low threshold ≤ 0.5 V relative to this pin.
5 (IN+ B)	Amplifier B non-inverting input	Independent input for second channel; shares same electrical specs and layout rules as IN+ A.
6 (IN− B)	Amplifier B inverting input	Matches IN− A performance; differential input voltage rating ±V_CC.
7 (OUT B)	Amplifier B output	Identical output drive and rail-swing behavior to OUT A; fully isolated from other channels.
8 (SHDN)	Global shutdown control	Active-low logic input; pulls all four outputs to high-Z when ≤ 0.5 V; must not float.
9 (OUT C)	Amplifier C output	Third independent output; same AC/DC specs and thermal derating as OUT A/B.
10 (IN− C)	Amplifier C inverting input	Third channel input; matches bias current and CMR (70–75 dB) of other inputs.
11 (IN+ C)	Amplifier C non-inverting input	Third channel positive input; supports same Vicm range and noise performance (16 nV/√Hz @ 1 kHz).
12 (V_CC+)	Positive supply rail	Accepts 2.5–5.5 V; requires local 10 nF decoupling per supply pin per datasheet recommendation.
13 (IN+ D)	Amplifier D non-inverting input	Fourth channel input; identical offset drift (1 µV/°C) and THD+N (0.001% @ 1 kHz) to others.
14 (IN− D)	Amplifier D inverting input	Final channel input; maintains 90–100 dB large-signal voltage gain across temperature.

Key Features

Feature	Design Value
Automotive qualification	AEC-Q100 Grade 1 certified - validated for 15-year lifetime in under-hood environments with thermal cycling and humidity exposure.
Rail-to-rail output	Drives within 150 mV of both rails into 2 kΩ - maximizes usable ADC input range in 3.3 V or 5 V systems.
Low input offset drift	1 µV/°C max over -40°C to +125°C - ensures <1.2 mV total offset shift across full operating range.
High ESD tolerance	4 kV HBM (non-SHDN pins), 3.5 kV HBM (SHDN pin) - eliminates need for external protection in most automotive PCBs.
Fast shutdown recovery	300 ns turn-on time (to ±200 mV) - enables burst-mode sensing with minimal latency penalty.

Applications

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
TSV854IPT	Lower power (180 µA/ch), lower GBP (1.3 MHz), no shutdown pin	Better for always-on ultra-low-power monitoring; unsuitable for burst-mode or shutdown-critical designs	Select when power budget <720 µA total dominates over bandwidth and shutdown needs.
LMV324IPT	Higher V_io (7 mV max), no shutdown, lower GBP (1 MHz), non-automotive grade	Cost-sensitive consumer applications only; fails AEC-Q100 and wide-temp validation	Use only in non-automotive, commercial-temp (-20°C to +70°C) cost-driven designs.

Compared with TSV854IPT and LMV324IPT, LMV824IPT uniquely balances automotive qualification, 5.5 MHz bandwidth, and nanowatt shutdown - making it the sole choice for AEC-Q100-compliant, battery-conscious, multi-channel signal chains requiring fast wake-up and precision.

FAQ

What is the maximum allowable supply voltage for LMV824IPT?

The absolute maximum supply voltage is 6 V, but the recommended operating range is 2.5 V to 5.5 V per the datasheet. Operation above 5.5 V risks permanent damage and invalidates AEC-Q100 qualification. Thermal derating begins above 5 V due to increased junction temperature at full load.

Does LMV824IPT support true rail-to-rail input?

No - LMV824IPT has rail-to-rail *output* but its input common-mode range extends only to V_CC− − 0.2 V and V_CC+ − 1 V. It does not accept inputs at the positive rail, limiting use in certain single-supply follower configurations where Vin = V_CC+.

Can the SHDN pin be left unconnected?

No - the SHDN pin must never be left floating. Per Section 4.7 of the datasheet, it must be actively pulled to either V_CC+ (to enable) or V_CC− (to disable). An unconnected SHDN pin causes undefined output states and potential latch-up risk.

Is LMV824IPT pin-compatible with LMV324IPT?

Yes - both use TSSOP14 packaging with identical pinout for all four amplifier channels and supply pins. However, LMV824IPT adds the SHDN pin at Pin 8 (replacing NC on LMV324IPT), so direct replacement requires board-level modification to route shutdown control.
