Product details
Overview
LMV932IDRG4 from Texas Instruments is a dual rail-to-rail input/output operational amplifier optimized for 1.8-V to 5-V single-supply operation, delivering 1.4 MHz gain bandwidth, 100 μA per channel supply current, and output swing within 80 mV of rails into 600 Ω - ideal for low-voltage battery-powered sensor signal conditioning in portable audio and energy metering systems.
For engineers reviewing the LMV932IDRG4 datasheet, LMV932IDRG4 pinout, LMV932IDRG4 application, or LMV932IDRG4 equivalent, key selection criteria include its –40°C to 125°C operating range, SOIC-8 package compatibility, rail-to-rail common-mode input extending 200 mV beyond rails, and verified performance at 1.8-V supply with <4 mV max input offset voltage.
Technical Context
The LMV932IDRG4 employs a CMOS input stage enabling rail-to-rail input common-mode range (VCC– – 0.2 V to VCC+ + 0.2 V) and Class AB output stage supporting rail-to-rail output swing under load. Its 1.4 MHz unity-gain bandwidth and 0.35 V/μs slew rate are specified across 1.8–5 V supplies.
Designed for single-supply use, it features 101 dB open-loop DC gain, 75 dB CMRR at 25°C, and 70 dB PSRR - all validated over full temperature range. Input bias current remains ≤75 nA, and input offset voltage is guaranteed ≤7.5 mV across –40°C to 125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5 V - enables direct interface with Li-ion or two-cell alkaline batteries without level-shifting. |
| Gain Bandwidth Product | 1.4 MHz - supports stable unity-gain buffer and low-frequency active filtering up to ~100 kHz. |
| Supply Current per Channel | 100 μA - allows integration into always-on monitoring circuits with sub-200 μA total quiescent draw. |
| Input Offset Voltage (max) | 7.5 mV - ensures ≤0.75% error in 1-V full-scale sensor amplification without trimming. |
| Rail-to-Rail Output Swing | Within 80 mV of rails into 600 Ω - preserves dynamic range in 1.8-V systems where headroom is critical. |
| Input Common-Mode Range | VCC– – 0.2 V to VCC+ + 0.2 V - accepts signals below ground or above VCC, simplifying single-supply transducer interfacing. |
| Operating Temperature | –40°C to 125°C - qualified for automotive cabin and industrial control environments without derating. |
Pinout & Package
LMV932IDRG4 is housed in an 8-pin SOIC (D) package with standard JEDEC outline and 1.27 mm pitch. Pin 1 is marked by a beveled corner or dot; device orientation follows TI's top-view convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output channel A - drives loads up to 600 Ω while maintaining rail-to-rail swing. |
| 2 | IN− A | Inverting input for channel A - high-impedance CMOS node with ≤75 nA bias current. |
| 3 | IN+ A | Non-inverting input for channel A - accepts common-mode voltages from VCC– – 0.2 V to VCC+ + 0.2 V. |
| 4 | VCC− | Negative supply rail (GND in single-supply config) - must be connected to system ground or negative rail. |
| 5 | VCC+ | Positive supply rail - accepts 1.8–5 V; decoupling capacitor required within 1 cm of this pin. |
| 6 | IN+ B | Non-inverting input for channel B - electrically isolated from channel A with ≥123 dB amplifier-to-amplifier isolation. |
| 7 | IN− B | Inverting input for channel B - matched offset and bias characteristics to channel A for differential pair use. |
| 8 | OUT B | Inverting amplifier output channel B - independent output stage with identical drive capability to pin 1. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 1.8-V supply range - no external level shifters needed for sensor interfaces. |
| 100 μA per channel supply current | Supports ultra-low-power wake-up circuits and battery-operated data loggers with multi-year runtime. |
| 1.4-MHz gain bandwidth at 1.8 V | Permits stable closed-loop gain ≥10 at 100 kHz - suitable for anti-aliasing and reconstruction filters. |
| 200-mV beyond-rail input common-mode range | Accepts transducer outputs that swing slightly below GND or above VCC - eliminates clamping diodes. |
| –40°C to 125°C operation | Validated performance across automotive under-hood and industrial PLC temperature extremes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9002IDR | Lower 0.65-mV max VIO, higher 1-MHz GBW, but 170-μA/channel supply current - 70% higher quiescent draw. | Better DC accuracy and speed; less suitable for multi-year battery life requirements. | Select TLV9002IDR when offset-critical sensor front-ends demand <1-mV error at room temperature. |
| OPA2314AIDR | Higher 3.5-mV max VIO, lower 100-μA/channel ICC, but only 1.2-MHz GBW and limited 1.8-V validation - not characterized below 2.7 V. | Lower power than LMV932IDRG4 but unverified for 1.8-V operation; unsuitable for single-cell Li-ion systems. | Select OPA2314AIDR only for 2.7–5.5-V systems where extended low-voltage operation is not required. |
Compared with TLV9002IDR and OPA2314AIDR, LMV932IDRG4 uniquely balances 1.8-V operability, 100-μA/channel efficiency, and 7.5-mV VIO tolerance - making it the only option qualified for cost-sensitive, wide-temperature, single-cell battery applications requiring production longevity.

FAQ
Is LMV932IDRG4 still in production?
No - LMV932IDRG4 is marked OBSOLETE in TI's official packaging addendum dated October 2016. It remains available through authorized distributors' legacy inventory and Aetrix Electronics' consigned stock, with full traceability and extended lifecycle support for existing designs.
What is the maximum output current capability of LMV932IDRG4?
LMV932IDRG4 delivers ±65 mA short-circuit output current at 5 V supply (sinking), and ±80 mA (sourcing) at 2.7 V, per channel. Under normal 600-Ω load conditions, it maintains rail-to-rail swing with <80 mV dropout - verified across –40°C to 125°C.
Does LMV932IDRG4 support true single-supply operation with input signals below ground?
Yes - LMV932IDRG4's input common-mode range extends to VCC– – 0.2 V, allowing inputs as low as –0.2 V relative to GND when VCC– = 0 V. This enables direct connection to transducers with negative-going outputs without external level-shifting circuitry.
What is the thermal resistance (θJA) of the SOIC-8 package used by LMV932IDRG4?
The SOIC-8 (D) package for LMV932IDRG4 has a junction-to-ambient thermal resistance (θJA) of 97°C/W, measured per JESD 51-7 on a 1-inch² 2-layer board with 2-oz copper. This value assumes standard JEDEC test board layout and no internal heatsinking.
Can LMV932IDRG4 drive capacitive loads up to 1000 pF without instability?
Yes - LMV932IDRG4 is characterized to drive up to 1000 pF with minimal ringing into a 600-Ω load, as confirmed in Figure 10 and Figure 11 of the SLOS441G datasheet. Phase margin remains ≥67° at 1.8 V with CL = 1000 pF, ensuring stable unity-gain buffer operation.
