ADI AD7740YRM

电压至频率1 MHz±50ppm/°C

Overview

The AD7740YRM is a low-cost, ultrasmall synchronous Voltage-to-FrequencyConverter (VFC). It works from a single 3.0 V to3.6 V or 4.75 V to 5.25 V supply consuming 0.9 mA. The AD7740is available in an 8-lead SOT-23 and also in an 8-lead MSOPpackage. Small package, low cost and ease of use were majordesign goals for this product. The part contains an on-chip 2.5 Vbandgap reference but the user may overdrive this using anexternal reference. This external reference range includes VDD.

The AD7740YRM (Y Grade) is guaranteed over the automotivetemperature range of –40°C to +105°C. The AD7740YRM (K Grade)is guaranteed from 0°C to 85°C.
