LMV321, LMV358, LMV324 Low cost, low power, input/output rail-to-rail operational amplifiers Datasheet - production data Features • Operating range from VCc = 2.7 to 6 V • Rail-to-rail input and output • Extended Vicm (VDD - 0.2 V to VCc + 0.2 V) • Low supply current (145 pA) • Gain bandwidth product (1 MHz) Related products • See LMV321L, LMV358L, LMV324L for newer technological version • See TSV851, TSV852, TSV854 for enhanced performances Applications • Battery powered electronic equipment • Personal medical care (glucose meters) • Laptops Description The LMV321/358/324 family (single, dual, and quad) answers the need for low cost, general-purpose operational amplifiers. They operate with voltages as low as 2.7 V and feature both input and output rail-to-rail, 145 pA consumption current, and 1 MHz gain bandwidth product (GBP). With such a low consumption and a sufficient GBP for many applications, these op amps are well suited for any kind of battery supplied and portable equipment application. The LMV321 device is housed in the spacesaving 5-pin SOT23-5 package, which simplifies board design. The SOT23-5 has two pinning configurations to answer all application requirements.

Absolute maximum ratings and operating conditions Table 1: Absolute maximum ratings Notes: ( 'All voltage values, except differential voltage are with respect to network terminal. (2) The differential voltage is the non-inverting input terminal with respect to the inverting input terminal. If Vid > ±1 V, the maximum input current must not exceed ±1 mA. In this case (Vid > ±1 V), an input series resistor must be added to limit input current. (3) (3)Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-circuits on all amplifiers. All values are...
