Product details

Overview

LMV820ILT from STMicroelectronics is a single-channel, rail-to-rail output operational amplifier with integrated shutdown control, designed for precision signal conditioning in low-voltage, power-constrained systems. It delivers 5.5 MHz gain bandwidth, 0.8 mV max input offset voltage (25°C), 400 µA max supply current at 5 V, and operates from 2.5 V to 5.5 V across –40°C to +125°C - enabling use in automotive sensor front-ends and portable medical monitors.

For engineers reviewing the LMV820ILT datasheet, LMV820ILT pinout, LMV820ILT application, or LMV820ILT equivalent, key selection criteria include shutdown current (≤50 nA), rail-to-rail output swing (≤150 mV from rails), input common-mode range (to V_CC–1 V), and guaranteed performance over extended temperature - critical for battery-powered instrumentation and automotive signal chains.

Technical Context

The LMV820ILT implements a CMOS-input, rail-to-rail output op-amp architecture optimized for low-voltage operation. Its input stage supports common-mode voltages down to V_CC– – 0.2 V and up to V_CC+ – 1 V without phase reversal, while the output stage drives loads to within 150 mV of either rail under 2 kΩ loading.

Shutdown functionality is controlled via a dedicated SHDN pin (logic high = active, logic low = disabled), reducing supply current to ≤50 nA at 25°C and placing the output in high-impedance state. Turn-on/turn-off times are specified at 300 ns and 20 ns respectively, supporting fast power-gating in duty-cycled sensing systems.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	2.5 V to 5.5 V - enables direct interface with Li-ion battery (3.0–4.2 V) and 3.3 V logic without level-shifting.
Gain Bandwidth Product	5.5 MHz - supports stable unity-gain buffer configurations up to ~5 MHz, outperforming LMV321 in bandwidth-limited filtering.
Input Offset Voltage	0.8 mV max at 25°C - reduces DC error in precision transducer amplification without trimming.
Supply Current per Channel	400 µA max at 5 V - extends battery life in always-on sensor nodes (e.g., >1-year runtime on CR2032).
Shutdown Current	50 nA max at 25°C - enables micro-power sleep modes in portable ECG or glucose meters.
Rail-to-Rail Output Swing	≤150 mV from V_CC or GND with 2 kΩ load - maximizes dynamic range in 3.3 V ADC interfaces.
Operating Temperature	–40°C to +125°C - qualified for under-hood automotive applications and industrial edge sensors.

Pinout & Package

LMV820ILT is housed in a SC70-5 (SOT323-5) package - a 1.25 mm × 1.65 mm surface-mount outline with 0.65 mm pitch, optimized for space-constrained PCBs in wearables and automotive modules.

Pin/Terminal	Circuit Role	Design Meaning
1 (IN–)	Inverting Input	Differential input node; supports common-mode range to V_CC– – 0.2 V and V_CC+ – 1 V.
2 (IN+)	Non-inverting Input	Differential input node; matched bias current (≤120 nA typ) minimizes offset drift in high-Z sensor interfaces.
3 (V–)	Negative Supply / Ground	Reference for single-supply operation; tied to system GND in 2.5–5.5 V applications.
4 (SHDN)	Shutdown Control Input	Active-high logic input; must be driven to V_CC– (GND) to enter ≤50 nA shutdown mode.
5 (OUT)	Amplifier Output	Rail-to-rail capable output; sinks/supplies ≥26 mA (2.7 V) or ≥43 mA (5 V) into resistive loads.

Key Features

Feature	Design Value
Automotive qualification	AEC-Q100 Grade 1 compliant - validated for reliability in engine control, ADAS sensor modules, and body electronics.
High ESD tolerance	4 kV HBM (non-SHDN pins), 3.5 kV HBM (SHDN pin) - withstands handling and board-level ESD events without latch-up.
Low input bias current	60–120 nA typ (25°C) - preserves signal integrity in high-impedance pH or thermopile sensor circuits.
Stable with capacitive loads	Phase margin ≥60° with C_L ≤ 200 pF - eliminates need for isolation resistors in ADC driver or filter stages.
Input offset drift	1 µV/°C max - ensures <±2 mV total offset shift over –40°C to +125°C, critical for uncalibrated industrial sensors.

Equivalent & Alternatives

The following parts are listed as comparable options for similar low-power, rail-to-rail op-amp applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TSV851ILT	Lower supply current (180 µA max at 5 V), same 5.5 MHz GBW, no shutdown pin.	Preferred where ultra-low quiescent power is prioritized over power-gating capability.	Select when shutdown is unnecessary and battery life is paramount; requires external enable circuitry if power control needed.
LMV321IDBVR	Higher offset (7 mV max), lower GBW (1 MHz), no shutdown, wider supply range (2.7–5.5 V).	Suitable for cost-sensitive, non-automotive consumer applications with relaxed accuracy.	Choose only for legacy designs or budget-driven projects where 5.5 MHz bandwidth and AEC-Q100 compliance are not required.

Compared with TSV851ILT and LMV321IDBVR, the LMV820ILT uniquely combines automotive qualification, integrated shutdown, and superior DC precision - making it the optimal choice for new designs requiring guaranteed performance in harsh, power-limited environments.

FAQ

What is the maximum allowable supply voltage for LMV820ILT?

The absolute maximum supply voltage is 6 V, but the recommended operating range is 2.5 V to 5.5 V. Operation above 5.5 V risks permanent damage and invalidates parametric guarantees - especially critical in automotive 12 V systems where transient spikes require external clamping.

Can LMV820ILT drive a 600 Ω load while maintaining rail-to-rail output swing?

No - rail-to-rail swing is specified for 2 kΩ loads (≤150 mV from rails). With 600 Ω, output swing degrades to ≤400 mV from rails at 5 V supply. For 600 Ω applications, verify output voltage compliance in simulation using the provided macromodel or measure with actual load.

Is the SHDN pin internally pulled up or down?

The SHDN pin has no internal pull-up or pull-down; it must be actively driven to V_CC– (GND) for shutdown or V_CC+ for operation. Leaving it floating may cause undefined behavior or increased current consumption due to leakage paths.

Does LMV820ILT require external compensation for unity-gain stability?

No - the LMV820ILT is unity-gain stable with capacitive loads up to 200 pF, as confirmed by ≥60° phase margin in datasheet Figure 10. No external compensation components are needed for standard buffer or inverting amplifier configurations.
