Data transceivers reduce component count by up to 80% compared to discretes

The ADM2682E and ADM2687E single-chip 5-kVrms signal- and power-isolated RS-485 data transceivers are offered as the first of their kind to meet the safety isolation requirements of high-voltage systems in motor, power, and energy control systems. The parts reduce component count by up to 80% compared to discrete competitive options. In addition, packaged in a single 10 x 13-mm surface-mount package with greater than 8-mm minimum creepage and clearance, the transceivers occupy 70% less board space than the multiple discrete components typically used.

Both products are designed with the company’s iCoupler isolation technology and combine a three-channel isolator, a three-state differential line driver, and a differential input receiver based on isoPower isolated dc/dc converter technology. The ADM2682E and ADM2687E achieve data rates of 16 Mbits/s and 500 kbits/s, respectively. Housed in 16-lead wide-body SOIC packages, the new data transceivers also feature ±15-kV ESD protection on the bus pins. Supply voltage is 5 or 3.3 V, and the temperature range is from –40° to 85°C. (Ea/1,000: ADM2682E, $7.50; ADM2687E, $6.50 — prod qty, June 2011.)
