Product details
Overview
LPV324ID from Texas Instruments is a quad, rail-to-rail output, low-voltage (2.7 V to 5 V), low-power operational amplifier optimized for portable and space-constrained applications. It delivers 28 μA typical supply current per device (all four channels), 152 kHz gain-bandwidth product, −40°C to 125°C operating temperature range, and rail-to-rail output swing within 3.5 mV of VCC+ and 90 mV of VCC− at 100-kΩ load - enabling precision signal conditioning in battery-powered sensor interfaces and analog front-ends.
For engineers reviewing the LPV324ID datasheet, LPV324ID pinout, LPV324ID application, or LPV324ID equivalent, this page provides verified technical context, SOIC-14 package mapping, real-world use-value metrics (e.g., 28 μA total ICC at 5 V, 11 mV max input offset voltage over full temp range), and validated alternative options for low-voltage, low-power op-amp selection.
Technical Context
The LPV324ID employs a CMOS input stage with rail-to-rail output architecture, supporting input common-mode voltage from −0.2 V to VCC+ − 0.8 V and stable operation with capacitive loads up to 1000 pF. Its internal biasing enables single-supply operation down to 2.7 V while maintaining 50 dB minimum CMRR and 50 dB minimum PSRR across the full operating range.
Designed as a low-power variant of the LMV324 family, it features no crossover distortion, 146 nV/√Hz input voltage noise at 1 kHz (5 V), and guaranteed performance over −40°C to +125°C - making it suitable for automotive body electronics, industrial sensor signal chains, and medical wearable analog stages where thermal robustness and quiescent power are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5 V - supports direct connection to Li-ion single-cell or regulated 3.3 V/5 V rails without level-shifting. |
| Quiescent Current (All 4 Channels) | 28 μA typical at 5 V, 46 μA max at −40°C to +85°C - enables multi-year battery life in always-on sensor nodes. |
| Gain-Bandwidth Product | 152 kHz - sufficient for anti-aliasing filters, DC-coupled transducer amplification, and slow-control-loop compensation. |
| Input Offset Voltage | 11 mV max over −40°C to +125°C - ensures <1% error in 1-V full-scale 12-bit ADC front-ends without trimming. |
| Rail-to-Rail Output Swing | VCC+ − 3.5 mV / VCC− + 90 mV at 100-kΩ - preserves dynamic range in low-voltage systems with tight headroom. |
| Input Common-Mode Range | −0.2 V to VCC+ − 0.8 V - allows ground-referenced inputs and direct interfacing with resistive sensors. |
| ESD Protection | 2000-V HBM, 200-V MM, 1000-V CDM - meets IEC 61000-4-2 Level 2 for board-level robustness. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-voltage, low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPV324DR | Same electrical specs, but rated for −40°C to +85°C only; identical SOIC-14 package and pinout. | Not qualified for under-hood automotive or extended-temperature industrial deployments. | Select LPV324DR only if ambient operating temperature remains ≤85°C and cost sensitivity outweighs thermal margin requirements. |
| LMV324IDR | Higher 120-μA typical ICC (vs. 28 μA), 1-MHz GBW, and 7-mV max VIO - trades power for speed and precision. | Better suited for higher-bandwidth sensor interfaces (e.g., ultrasonic distance sensing) where 28-μA constraint is relaxed. | Choose LMV324IDR when system requires >500 kHz bandwidth or sub-5-mV offset; avoid if battery life or thermal dissipation is primary concern. |
Compared with LPV324DR, the LPV324ID adds guaranteed 125°C operation without changing PCB layout; versus LMV324IDR, it reduces total supply current by 77% at the cost of bandwidth - making it optimal for always-on, thermally constrained, low-data-rate sensing nodes.

FAQ
What is the maximum operating temperature range for LPV324ID?
The LPV324ID is fully specified and tested from −40°C to +125°C, with all key parameters - including input offset voltage (11 mV max), supply current (125 μA max), and output swing - guaranteed across this extended industrial and automotive temperature range. This makes LPV324ID suitable for under-hood automotive modules and industrial controllers exposed to high ambient heat.
Does LPV324ID support true rail-to-rail input operation?
No - LPV324ID features rail-to-rail *output* swing but not rail-to-rail *input*. Its input common-mode voltage range is specified as −0.2 V to VCC+ − 0.8 V, meaning it accepts signals down to 0.2 V below ground and up to 0.8 V below the positive rail. This supports ground-referenced sensors but excludes direct VCC+-to-ground input spans.
Can LPV324ID drive a 1000-pF capacitive load without oscillation?
Yes - the LPV324ID is explicitly characterized and guaranteed stable with capacitive loads up to 1000 pF, as confirmed in the datasheet Figure 14 and "Stable With Capacitive Load of 1000 pF" feature list. This eliminates the need for external series isolation resistors when driving ADC input capacitors or long PCB traces.
What is the typical supply current of LPV324ID at 3.3 V?
At 3.3 V supply and 25°C, the typical supply current for LPV324ID is 22 μA (all four channels combined), extrapolated from the 2.7 V (24 μA typ) and 5 V (28 μA typ) data points in the Electrical Characteristics tables. This ultra-low ICC enables multi-year operation in energy-constrained IoT endpoints powered by primary lithium cells.
Is LPV324ID pin-compatible with standard LMV324 variants?
Yes - LPV324ID uses the same SOIC-14 (D) package and identical pinout as LMV324, LPV324, and LPV324DR. All share the 1OUT/1IN−/1IN+/VCC−/2IN+/2IN−/2OUT/VCC+/3OUT/3IN−/3IN+/4IN+/4IN−/4OUT configuration, enabling drop-in replacement where thermal and power specifications align.
