AD7740YRM 製品詳細
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 full-scale output frequency is synchronous with the clocksignal on the CLKIN pin. This clock can be generated with theaddition of an external crystal (or resonator) or supplied from aCMOS-compatible clock source. The part has a maximuminput frequency of 1 MHz.
For an analog input signal that goes from 0 V to VREF, the outputfrequency goes from 10% to 90% of fCLKIN. In buffered mode,the part provides a very high input impedance and accepts arange of 0.1 V to VDD – 0.2 V on the VIN pin. There is alsoan unbuffered mode of operation that allows VIN to go from–0.15 V to VDD + 0.15 V. The modes are interchangeable usingthe BUF pin.
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.
