LMV7271/LMV7275/LMV7272 Single & Dual, 1.8V Low Power Comparators with Rail-to-Rail

Input

Check for Samples: LMV7271

FEATURES

DESCRIPTION

The LMV727X are rail-to-rail input low power

comparators, which are characterized at supply

voltage 1.8V, 2.7V and 5.0V. They consume only 9uA

supply current per channel while achieving a 800ns

propagation delay.

•

(V_S= 1.8V, T_A= 25°C, Typical values unless

specified).

•

Single or Dual Supplies

Ultra low supply current 9µA per channel

Low input bias current 10nA

The LMV7271/LMV7275 (single) are available in

SC70 and SOT-23 packages. The LMV7272 (dual) is

available in DSBGA package. With these tiny

packages, the PC board area can be significantly

reduced. They are ideal for low voltage, low power

and space critical designs.

Low input offset current 200pA

Low guaranteed V_OS4mV

Propagation delay 880ns (20mV overdrive)

Input common mode voltage range 0.1V

beyond rails

The LMV7271/LMV7272 both feature a push-pull

output stage which allows operation with minimum

APPLICATIONS

LMV7275 features an open drain output stage that

allows for wired-OR configurations. The open drain

output also offers the advantage of allowing the

output to be pulled to any voltage up to 5.5V,

regardless of the supply voltage of the LMV7275.

•

Mobile communications

Laptops and PDA's

Battery powered electronics

General purpose low voltage applications

The LMV727X are built with Texas Instruments'

advance submicron silicon-gate BiCMOS process.

They all have bipolar inputs for improved noise

performance and CMOS outputs for rail-to-rail output

swing.
