Texas Instruments LMV822D

Overview

LMV822D from Texas Instruments is a dual, rail-to-rail output operational amplifier optimized for low-voltage (2.5 V to 5 V), low-power applications. It delivers 5.5 MHz gain bandwidth, 1.9 V/μs slew rate at 5 V, and 0.5 mA typical supply current per amplifier across –40°C to 85°C. It serves as a signal-conditioning and buffering IC in portable sensor interfaces and battery-powered analog front-ends.

For engineers reviewing the LMV822D datasheet, LMV822D pinout, LMV822D application, or LMV822D equivalent, key selection criteria include its rail-to-rail output swing (4.85 V at 5 V supply into 2 kΩ), input common-mode range extending to ground, and SOIC-8 package compatibility with space-constrained industrial and consumer PCB layouts.

Technical Context

The LMV822D implements a CMOS input stage with rail-to-rail output stage using complementary push-pull drivers, enabling full-swing operation from 2.5 V to 5 V supplies. Its architecture eliminates crossover distortion and supports single-supply operation with input voltage range including ground.

It achieves stable unity-gain performance with 64.2° phase margin at 5 V and 600 Ω load, and maintains >135 dB amplifier-to-amplifier isolation-critical for dual-channel signal integrity in mixed-signal systems.

FAQ

What is the operating temperature range for LMV822D?

The LMV822D is characterized for operation from –40°C to +85°C. This range is validated per TI's SLOS434I datasheet and applies to all electrical specifications including input offset voltage, gain bandwidth, and output swing. The LMV822D is not rated for automotive-grade (–40°C to +125°C) operation; for that, the LMV822ID variant must be used. LMV822D remains fully functional and specified across its entire industrial temperature range.

Does LMV822D support true rail-to-rail input?

No, LMV822D does not support rail-to-rail input. Its input common-mode voltage range extends from –0.2 V to VCC+ – 0.7 V (e.g., –0.2 V to 4.3 V at 5 V supply), which includes ground but does not reach the positive rail. However, it does provide rail-to-rail output swing - typically within 100 mV of both rails under 2 kΩ load. This makes LMV822D ideal for single-supply applications where input signals reference ground but output must maximize dynamic range.

What is the maximum capacitive load LMV822D can drive stably?

LMV822D is unity-gain stable with capacitive loads up to 22 pF when driving a 10 kΩ resistive load, as confirmed in Figure 18 of the SLOS434I datasheet. For heavier loads (e.g., >100 pF), external series resistance (≥100 Ω) at the output is recommended to maintain phase margin above 60°. Driving cables or ADC input capacitance directly may require isolation or compensation; the device is not designed for direct 1 nF load driving without added stability measures.

Is LMV822D pin-compatible with other dual op-amps in SOIC-8?

LMV822D uses the standard dual op-amp pinout (IN+, IN−, OUT, GND, IN+, IN−, OUT, VCC+) defined in JEDEC MS-012, matching industry conventions for SOIC-8 op-amps like LM358, TLV2462, and MCP6022. While pinout alignment is consistent, electrical differences - such as input stage type (CMOS vs. bipolar), supply current, and bandwidth - mean direct substitution requires validation of offset, noise, and stability in the target circuit. No manufacturer declares LMV822D as a drop-in replacement for other families.

What is the typical input bias current of LMV822D at 25°C?

The typical input bias current of LMV822D is 30 nA at 25°C, with a maximum of 150 nA over the full –40°C to +85°C operating range (per 5-V Electrical Characteristics table). This low bias current stems from its CMOS input stage and enables high-impedance sensor interfacing - for example, preserving accuracy with 1 MΩ source impedances where voltage error remains below 30 μV. Bias current doubles approximately every 10°C rise, remaining well below 500 nA even at 85°C.
