TLV3012AIDBVT集成电路（IC）的比较器规格书PDF中文资料

TLV3012AIDBVT属于集成电路（IC）的比较器。由德州仪器制造生产的TLV3012AIDBVT比较器逻辑比较器系列产品用于根据以数字格式表示的信息比较结果来生成输出；身份型比较器指示两个输入是否相同，幅度型比较器还指示两个输入不相同时哪个较大。它们不同于比较两个模拟输入幅度的器件，后者称为线性比较器且单独分类。

3 Description

The TLV3011 is a low-power, open-drain output

comparator; the TLV3012 is a push-pull output

comparator. Both devices feature an uncommitted onchip

voltage reference and have a 5 μA (maximum)

quiescent current, an input common-mode range

200 mV beyond the supply rails, and single-supply

operation from 1.8 V to 5.5 V. The integrated 1.242

V series voltage reference offers low 100 ppm/°C

(maximum) drift, is stable with up to 10 nF capacitive

load, and can provide up to 0.5 mA (typical) of output

current.

The TLV3011B and TLV3012B B versions add

power-on-reset (POR), fail-safe inputs, built-in

hysteresis, a lower minimum supply voltage of 1.65

V and a 3.1 μA maximum quiescent current.

The family is available in both the tiny SOT23-6

package for space-conservative designs, and in the

SC-70 package for even greater board area savings.

All versions are specified for the temperature range of

–40°C to +125°C.
