Product details
Overview
LMV824PW 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 instrumentation.
For engineers reviewing the LMV824PW datasheet, LMV824PW pinout, LMV824PW application, or LMV824PW equivalent, key selection criteria include its rail-to-rail output swing down to 100 mV from rails at 2 kΩ load, –40°C to 85°C operating range, and TSSOP-14 package compatibility with high-density PCB layouts.
Technical Context
The LMV824PW integrates four independent voltage-feedback op-amps sharing a common 2.5–5.5 V single-supply rail. Its input stage supports common-mode voltage down to ground (–0.3 V) and up to VCC–0.2 V, while the output stage achieves rail-to-rail swing with sourcing/sinking capability of ≥12 mA at 5 V.
Designed for stability with capacitive loads up to 22 pF, it maintains 64.2° phase margin and 8.7 dB gain margin at 5 V with 600 Ω load - making it suitable for driving ADC inputs, active filters, and transimpedance stages without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.5 V to 5.5 V - enables direct interface with Li-ion, 3.3 V, and 5 V logic domains without level-shifting. |
| Gain Bandwidth | 5.5 MHz typ at 5 V - supports closed-loop gains up to ~55 at 100 kHz with stable phase margin. |
| Slew Rate | 1.9 V/μs typ at 5 V - ensures <1% THD for 10 kHz, 4.1 VP-P signals into 10 kΩ load. |
| Input Offset Voltage | 1 mV typ (25°C), 4 mV max (–40°C to 85°C) - enables DC-coupled sensor amplification with ≤0.1% error at unity gain. |
| Output Swing | 0.1 V to 4.9 V at 5 V supply, 2 kΩ load - delivers full dynamic range across 12-bit ADC reference spans. |
| Supply Current | 1 mA typ (all four amps, 5 V) - allows 10+ channels on a 10 mA budget in ultra-low-power systems. |
| CMRR | 72 dB min (–40°C to 85°C) - rejects common-mode noise in differential sensor interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV824DR | SOIC-14 package; identical electrical specs but larger footprint (8.65 mm × 3.91 mm vs. TSSOP-14's 5.0 mm × 4.4 mm). | Preferred for prototyping or through-hole assembly; less suitable for high-density portable PCBs. | Select LMV824DR only if board real estate permits SOIC or reflow compatibility with legacy footprints is required. |
| TLV2464IPW | Higher supply current (1.4 mA typ), lower GBW (6.4 MHz), and wider offset range (±2 mV max); operates down to 2.7 V only. | Better for higher-precision DC applications where offset drift matters more than speed; not rated for 2.5 V operation. | Choose TLV2464IPW when offset drift <1 μV/°C is critical and 2.5 V operation is unnecessary. |
Compared with LMV824DR and TLV2464IPW, the LMV824PW uniquely balances ultra-small TSSOP-14 packaging, 2.5 V minimum supply, and 5.5 MHz bandwidth - making it optimal for next-generation portable medical and industrial edge devices where size and low-voltage operation are non-negotiable.

FAQ
What is the operating temperature range for the LMV824PW?
The LMV824PW is characterized for operation from –40°C to 85°C. This range is confirmed in the official Texas Instruments SLOS434I datasheet under "Recommended Operating Conditions" and applies specifically to the LMV824PW variant with TSSOP-14 packaging and standard-grade qualification. The LMV824IPW variant extends to 125°C.
Does the LMV824PW support true rail-to-rail input operation?
No, the LMV824PW features rail-to-rail *output* swing but not rail-to-rail input. Its input common-mode voltage range extends from –0.3 V to VCC–0.2 V, allowing ground-referenced inputs but not full rail-to-rail input capability. This is explicitly stated in the "Common-mode input voltage range" parameter table for 5-V operation in the LMV8xx datasheet.
Can the LMV824PW drive a 600 Ω load effectively?
Yes, the LMV824PW can source and sink ≥12 mA at 5 V supply, enabling direct drive of 600 Ω loads with output swing of 0.17 V to 4.84 V. This capability is verified in the "Output swing" specifications under 5-V conditions and confirmed by Figure 5 ("Sourcing Current vs Output Voltage") in the LMV824 datasheet.
Is the LMV824PW pin-compatible with other packages in the LMV824 family?
No - the LMV824PW (TSSOP-14) shares identical pinout with LMV824DR (SOIC-14) and LMV824DGVR (TVSOP-14), as confirmed by TI's package drawings and the top-view pin diagram labeled "LMV824 . . . D, DGV, OR PW PACKAGE". All three use the same 14-pin functional mapping, enabling drop-in replacement across these packages.
What is the typical supply current consumption of the LMV824PW at 3.3 V?
At 3.3 V supply, the LMV824PW draws approximately 0.85 mA typical total supply current for all four amplifiers, interpolated from the 2.7 V (0.72 mA typ) and 5 V (1.0 mA typ) values in the "ICC" parameter table. This value is consistent with the linear trend shown in Figure 3 ("Supply Current vs Supply Voltage") for the LMV824 device.
