Product Overview
The LMV7235 is a Texas Instruments low-power rail-to-rail comparator in the Signal_Chain category. The device uses an open-drain output and supports a recommended supply range of 2.7 to 5.5 V, with operation specified from -40 to 85 °C.
Package options are compact 5-pin formats: SOT-23 DBV at 2.90 mm x 1.60 mm and SC70 DGK at 2.00 mm x 1.25 mm. Thermal resistance is specified as 265 °C/W for the DBV SOT-23 package and 478 °C/W for the DGK SC70 package.
At 5 V, propagation delay is specified at 75 ns typical with 100 mV overdrive and 15 pF load. At 2.7 V, the comparable typical delay is 85 ns. Supply current is 65 µA typical at 5 V and 52 µA typical at 2.7 V under no-load, 25 °C conditions. These parameters support threshold comparison, rail-referenced sensing, and low-current signal decision functions.

Procurement Notes
When requesting a quote for LMV7235, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For analog and signal-chain sourcing, supply voltage, bandwidth, accuracy, noise level, package, temperature grade, input/output configuration and qualification requirements should be verified before approval.
FAQ
What output type does the LMV7235 provide?
The LMV7235 provides an open-drain comparator output. Output leakage is specified at 3 nA typical for LMV7235 only, and output rise time is specified at 100 ns typical at V+ = 5 V.
What supply range is specified for LMV7235 operation?
The recommended operating supply voltage range is 2.7 to 5.5 V for V+ - V-. The absolute maximum supply voltage rating is 6 V, which is a limit condition rather than the recommended operating range.
Which packages are listed for the LMV7235?
The listed package options are 5-pin SOT-23 DBV measuring 2.90 mm x 1.60 mm and 5-pin SC70 DGK measuring 2.00 mm x 1.25 mm. Junction-to-ambient thermal resistance is 265 °C/W for DBV and 478 °C/W for DGK.
What propagation delay values are specified at 5 V?
At V+ = 5 V with CLOAD = 15 pF, typical propagation delay is 75 ns with 100 mV overdrive, 82 ns with 50 mV overdrive, and 89 ns with 20 mV overdrive.
