AD654集成电路（IC）的V/FF/V转换器规格书PDF中文资料

AD654属于集成电路（IC）的V/FF/V转换器。由亚德诺半导体技术有限公司制造生产的AD654V/F 和 F/V 转换器压频转换集成电路 (IC) 监视输入电压并输出比例频率，以用于汽车传感、电池监测、模数转换和信号隔离等应用。频压转换 IC 输出与输入频率成比例的模拟电压，用于速度感应、转速计、巡航控制和触摸式开关等仪器和仪表。

PRODUCT DESCRIPTION

The AD654 is a monolithic V/F converter consisting of an input amplifier, a precision oscillator system, and a high current output stage. A single RC network is all that is required to set up any full scale (FS) frequency up to 500 kHz and any FS input voltage up to ± 30 V. Linearity error is only 0.03 for a 250 kHz FS, and operation is guaranteed over an 80 dB dynamic range. The overall temperature coefficient (excluding the effects of external components) is typically ±50 ppm/°C. The AD654 operates from a single supply of 5 V to 36 V and consumes only 2.0 mA quies cent current.
