14433型双积分A/D转换器具有价格便宜,外围电路简单,芯片自动调零,自动转换极性,抗共模干扰性强等特点。其输出数字量为—1999～1999,分辩力1/4000,接近12bitA/D转换器的精确度。但价格为普通12bit逐次逼近A/D转换器的1/15/1/20。对于普通的温度、速度、流量等等惯性模拟量,不失为一个低价高效的A/D转换器件。它与8051单片机配合,可广泛用于各种控制设备和仪表之中。
14433 dual-integrated A / D converter with low cost, simple peripheral circuits, the chip automatically zero, automatically switch polarity, anti-common-mode interference and so on. The output digital amount of -1999 ~ 1999, resolution of 1/4000, close to 12bitA / D converter accuracy. But the price for ordinary 12bit successive approximation A / D converter 1/15/1/20. For the ordinary temperature, speed, flow, etc. inertial analog, after all, a cost-effective A / D converter. It with the 8051 SCM, can be widely used in a variety of control equipment and instruments.
