Texas Instruments LMV358QDDUR

Overview

LMV358QDDUR from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for low-voltage (2.7 V to 5.5 V) single-supply operation, delivering 1 MHz unity-gain bandwidth, 1 V/μs slew rate, and 210 μA typical supply current per amplifier - used in signal conditioning stages of portable audio mixers and HVAC sensor interfaces.

For engineers reviewing the LMV358QDDUR datasheet, LMV358QDDUR pinout, LMV358QDDUR application, or LMV358QDDUR 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 VSSOP-8 package compatibility with space-constrained industrial control PCBs.

Technical Context

This dual op-amp uses CMOS input stage architecture enabling rail-to-rail output swing and common-mode input range extending to ground. It operates without crossover distortion across its full output swing, supporting precision DC-coupled amplification in battery-powered systems.

The device features internally compensated unity-gain stable design with 60° phase margin and 10 dB gain margin at 5 V supply. Its input bias current remains below 250 nA (typ) over temperature, ensuring minimal error in high-impedance sensor interfacing circuits.

FAQ

What is the maximum supply voltage rating for LMV358QDDUR?

The absolute maximum supply voltage for LMV358QDDUR 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 violates TI's stress rating limits and may compromise long-term reliability even if immediate failure does not occur.

Does LMV358QDDUR support true rail-to-rail input capability?

LMV358QDDUR does not provide rail-to-rail input - its common-mode input voltage range extends to GND but only up to VCC – 1.2 V (not to VCC). However, it does deliver rail-to-rail output swing, reaching within 60 mV of both supply rails under 10 kΩ load. This makes it ideal for single-supply applications where output headroom is critical but input signals remain referenced near ground.

What is the typical input offset voltage of LMV358QDDUR at room temperature?

The typical input offset voltage of LMV358QDDUR is 7 mV at TA = 25°C and VCC = 2.7 V, as documented in Section 7.5 Electrical Characteristics. The maximum guaranteed value across –40°C to 125°C is 9 mV. This parameter directly impacts DC accuracy in precision gain stages and sensor amplifiers - for example, causing up to ±7 mV error in a unity-gain buffer driving a 12-bit ADC with 3.3 V reference.

Can LMV358QDDUR drive capacitive loads without instability?

LMV358QDDUR is unity-gain stable but exhibits reduced phase margin with increasing capacitive load - Figure 7 shows stability degrades from 60° at 0 pF to ~30° at 500 pF. For loads >100 pF, TI recommends adding a series resistor (30–100 Ω) between amplifier output and capacitance to isolate the pole. Direct driving of >500 pF (e.g., long cables or LCD bias networks) requires external compensation or buffer isolation to prevent oscillation.

Is LMV358QDDUR pin-compatible with other dual op-amps in the LMV3xx family?

LMV358QDDUR shares identical pinout with LMV358IDR (SOIC-8) and LMV358MM (VSSOP-8), as confirmed in Section 6 Pin Configuration and Functions. All LMV358 variants use the same 1OUT/1IN–/1IN+/GND/VCC+/2OUT/2IN–/2IN+ ordering. However, it is not pin-compatible with LMV324 (quad) or LMV321 (single) due to differing channel count and pin assignments.
