Analog Devices AD537 Datasheet
The AD537 is a precision current‑to‑frequency converter that operates from a single supply of 4.5 V to 36 V (or dual supply ±5 V to ±18 V). It provides a frequency output from 0 kHz up to 150 kHz with low non‑linearity and a high‑impedance input stage for voltage‑to‑current conversion. The document includes full specifications, typical application circuits, calibration procedures, and protection guidelines.
Additional sections cover output interfacing to digital logic families, synchronous operation via the SYNC pin, temperature‑to‑frequency conversion, and two‑wire data transmission. Application examples illustrate how the AD537 can be used for voltage‑to‑frequency, temperature‑to‑frequency, and PLL‑based V‑to‑F conversions.
