Texas Instruments LMV358QDR

Overview

LMV358QDR from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for low-voltage single-supply operation (2.7 V to 5.5 V), delivering 1 MHz unity-gain bandwidth, 1 V/μs slew rate, and 210 μA typical supply current per amplifier - used in portable media players, HVAC sensor signal conditioning, and motor control feedback loops.

For engineers reviewing the LMV358QDR datasheet, LMV358QDR pinout, LMV358QDR application, or LMV358QDR equivalent, key selection criteria include rail-to-rail output swing down to 60 mV from rails at 10 kΩ load, input offset voltage ≤7 mV (typ), –40°C to 125°C operating temperature, and compatibility with space-constrained SOIC-8 and VSSOP-8 PCB layouts.

Technical Context

The LMV358QDR implements a CMOS input stage with rail-to-rail output stage using complementary bipolar transistors, enabling full-swing operation from GND to VCC+ across its specified supply range. Its architecture supports single-supply configurations without external level-shifting components.

It features a common-mode input voltage range extending to GND (–0.2 V minimum) and up to VCC+ – 0.2 V, with guaranteed performance over industrial temperature (–40°C to 125°C) and ESD robustness exceeding 2000-V HBM. No internal shutdown logic is present - unlike LMV324S - making it a fixed-function dual op-amp.

Key Specifications

Pinout & Package

LMV358QDR is available in SOIC-8 (D) and VSSOP-8 (DDU/DGK) packages. Both variants share identical pin mapping and thermal characteristics (RθJA = 97°C/W for SOIC-8, 210°C/W for VSSOP-8).

FAQ

What is the maximum supply voltage for LMV358QDR?

The absolute maximum supply voltage for LMV358QDR is 5.5 V, as specified in Section 7.1 Absolute Maximum Ratings. Operation above this voltage risks permanent damage. Recommended operating range is 2.7 V to 5.5 V, with full electrical specifications guaranteed across that span. Exceeding 5.5 V - even momentarily - violates TI's stress rating limits and may compromise long-term reliability.

Does LMV358QDR support true rail-to-rail input?

No, LMV358QDR does not support rail-to-rail input. Its common-mode input voltage range extends from –0.2 V to VCC+ – 0.2 V (at 2.7 V supply), meaning it accepts inputs down to GND but not beyond - and up to ~2.5 V at 2.7 V supply. This GND-to-(VCC–0.2 V) range enables single-supply use with sensors referenced to ground, but excludes inputs at the positive rail. LMV358QDR is rail-to-rail output only.

Is LMV358QDR pin-compatible with LM358?

Yes, LMV358QDR is pin-compatible with LM358 in SOIC-8 (D) package, sharing identical pinout (1OUT, 1IN–, 1IN+, GND, 2IN+, 2IN–, 2OUT, VCC+). However, LM358 operates from 3 V to 32 V and lacks rail-to-rail output - limiting its usefulness below 5 V. Replacing LM358 with LMV358QDR in existing 5 V designs requires no PCB changes but delivers improved output swing and lower supply current.

What is the typical input offset voltage of LMV358QDR?

The typical input offset voltage of LMV358QDR is 7 mV at 25°C and 2.7 V supply, with a maximum of 9 mV across the full –40°C to 125°C temperature range (Section 7.6). This value is measured differentially between IN+ and IN– pins. For precision DC applications, users should consider trimming or selecting higher-accuracy alternatives like TLV2372, as LMV358QDR's offset contributes directly to static gain error.

Can LMV358QDR drive capacitive loads without oscillation?

LMV358QDR can drive ≤100 pF capacitive loads stably without external compensation, as confirmed by Figure 7 (Stability vs Capacitive Load) in the datasheet. Driving >100 pF - such as long cables or ADC input capacitance - risks phase margin degradation and potential oscillation. For loads >100 pF, TI recommends adding a series resistor (≥100 Ω) between LMV358QDR output and the capacitive node to isolate the pole.
