Texas Instruments LMV822MM

Overview

LMV822MM from Texas Instruments is a dual, rail-to-rail output (RRO), low-voltage operational amplifier optimized for 2.5 V to 5.5 V single-supply operation. It delivers 5 MHz gain-bandwidth product, 1.4 V/µs slew rate, and 220 µA per amplifier supply current at 2.7 V - enabling precision signal conditioning in space-constrained portable electronics such as laptops and cellular handsets.

For engineers reviewing the LMV822MM datasheet, LMV822MM pinout, LMV822MM application, or LMV822MM equivalent, key selection criteria include its guaranteed rail-to-rail output swing into 600 Ω (≤160 mV from rail), ±3.5 mV max input offset voltage, −40°C to +85°C industrial temperature range, and SOIC-8/VSSOP-8 package compatibility.

Technical Context

The LMV822MM employs a CMOS input stage with ground-sensing common-mode input range (−0.3 V to 4.3 V at 5 V supply) and achieves stable unity-gain operation with capacitive loads up to several hundred pF. Its internal architecture supports high open-loop gain (>100 dB) and robust PSRR (85 dB) and CMRR (90 dB) across supply voltages.

Designed for low-noise, low-distortion performance, it exhibits 24 nV/√Hz input voltage noise at 1 kHz and 0.01% THD+N at 1 kHz with 4.1 V_PP output into 10 kΩ - making it suitable for audio preamplification and sensor signal amplification where DC accuracy and AC fidelity are both critical.

Key Specifications

Pinout & Package

LMV822MM is available in the 8-pin VSSOP package (3.00 mm × 3.00 mm), offering 45% board area reduction versus standard SOIC-8 while maintaining compatible footprint pitch (0.65 mm). This ultra-thin, leadless package supports high-density PCB layouts in portable equipment.

FAQ

What is the maximum operating temperature range for the LMV822MM?

The LMV822MM is specified for operation from −40°C to +85°C, meeting industrial temperature requirements. It is not rated for extended automotive temperature ranges; for −40°C to +125°C operation, the LMV822-N-Q1 variant must be selected, which is AEC-Q100 Grade 1 qualified. The LMV822MM's thermal resistance (R_θJA) is 193.9°C/W in VSSOP-8 package, requiring appropriate PCB copper area for sustained full-load operation at elevated ambient temperatures.

Does the LMV822MM support true rail-to-rail input operation?

No, the LMV822MM does not support rail-to-rail input. Its input common-mode voltage range extends from −0.3 V to 4.3 V at 5 V supply - meaning it accepts inputs down to 0.3 V below ground (enabling ground-sensing) but cannot reach the positive rail. The input stage is CMOS-based and optimized for low bias current, not full rail coverage. For true rail-to-rail input, consider TI's TLV2462 or MCP6022, though those differ in bandwidth and supply current.

Can the LMV822MM drive a 600 Ω load while maintaining rail-to-rail output swing?

Yes, the LMV822MM is explicitly characterized to deliver rail-to-rail output swing into 600 Ω loads: at 5 V supply, it swings to within 160 mV of each rail (i.e., 0.16 V to 4.84 V), and at 2.7 V supply, within 200 mV (0.20 V to 2.58 V). This capability is validated across temperature and process corners, and the device remains stable without external compensation - making it suitable for driving legacy audio lines, telecom interfaces, and ADC reference buffers requiring wide dynamic range.

What is the typical input voltage noise density of the LMV822MM?

The LMV822MM has a typical input voltage noise density of 24 nV/√Hz at 1 kHz and 5 V supply, as confirmed in Section 6.11 of the official datasheet. At 2.7 V supply, it measures 28 nV/√Hz (Section 6.9). This noise performance supports high-fidelity audio preamplification and low-level sensor signal amplification where signal amplitudes are in the mV range and bandwidth is limited to <100 kHz. Current noise is 0.25 pA/√Hz at 1 kHz, indicating suitability for medium-impedance sources.

Is the LMV822MM pin-compatible with other dual op-amps in VSSOP-8 package?

The LMV822MM uses the industry-standard VSSOP-8 pinout (pin 1 = Inverting Input A, pin 2 = Non-Inverting Input A, pin 3 = Output A, pin 4 = V−, pin 5 = Non-Inverting Input B, pin 6 = Inverting Input B, pin 7 = Output B, pin 8 = V+), matching TI's TLV2462, MCP6022, and many other dual op-amps in this package. However, electrical behavior differs - especially in supply current, bandwidth, and input structure - so functional substitution requires validation of loop stability, noise, and DC accuracy in the target application.
