Texas Instruments LMV824IDGVRE4

Overview

LMV824IDGVRE4 from Texas Instruments is a quad, rail-to-rail output operational amplifier optimized for low-voltage (2.5 V to 5.5 V), low-power applications. It delivers 5.5 MHz gain bandwidth, 1.9 V/μs slew rate, and 1 mA typical supply current at 5 V - enabling precision signal conditioning in space-constrained portable electronics such as medical sensors and battery-powered data acquisition systems.

For engineers reviewing the LMV824IDGVRE4 datasheet, LMV824IDGVRE4 pinout, LMV824IDGVRE4 application, or LMV824IDGVRE4 equivalent, key selection criteria include its –40°C to 125°C operating range, rail-to-rail output swing down to 100 mV from rails (at 2 kΩ load), input common-mode range extending to ground, and TVSOP-14 (DGV) package compatibility with high-density PCB layouts.

Technical Context

The LMV824IDGVRE4 integrates four independent amplifiers sharing a single 2.5–5.5 V supply, each featuring complementary-input-stage architecture that eliminates crossover distortion and supports true rail-to-rail output swing. Its input stage operates with common-mode voltage down to VCC− (ground in single-supply mode), enabling direct interfacing with sensors and ADC reference buffers.

Designed for stability with capacitive loads up to 22 pF and resistive loads ≥600 Ω, the device maintains ≥64.2° phase margin and 8.7 dB gain margin at 5 V, supporting robust closed-loop performance in transimpedance, active filter, and sensor interface configurations without external compensation.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating temperature for LMV824IDGVRE4?

The LMV824IDGVRE4 is characterized for operation from –40°C to +125°C, making it suitable for under-hood automotive, industrial control cabinets, and extended-temperature medical equipment. This rating is confirmed in the "Recommended Operating Conditions" table of the SLOS434I datasheet and applies specifically to the LMV824I-grade variants like LMV824IDGVRE4.

Does LMV824IDGVRE4 support true rail-to-rail input?

LMV824IDGVRE4 features rail-to-rail *output* swing but its input common-mode voltage range extends only to VCC− (ground) and up to VCC+ – 0.3 V. It does not support full rail-to-rail input; the upper limit is 0.3 V below VCC+, as specified in the VICR parameter (–0.3 V to 4.3 V at 5 V supply). This allows ground-referenced sensor interfacing but excludes direct VCC+-referenced signals.

What is the typical supply current for LMV824IDGVRE4 at 3.3 V?

At 3.3 V supply, LMV824IDGVRE4 draws approximately 0.85 mA typical total supply current (all four amplifiers), interpolated from the 2.7 V (0.72 mA typ) and 5 V (1.0 mA typ) ICC specifications in the LMV8xxI 2.7-V and 5-V Electrical Characteristics tables. This value is consistent with its low-power design target for battery-operated systems.

Can LMV824IDGVRE4 drive a 600 Ω load while maintaining rail-to-rail output?

Yes - LMV824IDGVRE4 delivers rail-to-rail output swing even into 600 Ω loads: at 5 V supply, it sources 2.5 V to 4.5 V and sinks 0.5 V to 2.5 V (VO high/low specs), achieving ≤0.3 V from each rail. This is verified in the "LMV8xx 5-V Electrical Characteristics" table under VO parameter with RL = 600 Ω test condition.

Is LMV824IDGVRE4 pin-compatible with LMV824DR?

No - LMV824IDGVRE4 uses the 14-pin TVSOP (DGV) package with 0.5 mm pitch, while LMV824DR uses the 14-pin SOIC (D) package with 1.27 mm pitch. Although both contain identical quad op-amp functionality and share the same pin function mapping (e.g., Pin 1 = 1OUT), their physical footprints and soldering requirements are incompatible without PCB redesign.
