AD654 Monolithic V/F Converter

Model No: AIC-00002

TK. 235.62

Availability: In stock


Category: Other IC

Supplier: Made in China

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. TheAD654 operates from a single supply of 5 V to 36 V and consumes only 2.0 mA quiescent current.

The low drift (4 µV/°C typ) input amplifier allows operation directly from small signals such as thermocouples or strain gauges while offering a high (250 M(ohm)) input resistance. Unlike most V/F converters, the AD654 provides a square-wave output, and can drive up to 12 TTL loads, optocouplers, long cables, or similar loads.

  • Operating Voltage:5 V to 36 V, ±5 V to ±18 V
  • Full-Scale Frequency Up to 500 kHz
  • Operating temperature:-40 to +85°C.
  • Low Power: 2.0 mA Quiescent Current
  • Low Offset: 1 mV
