Broadcom's ACPL-C87AT and ACPL-C87BT automotive isolation amplifiers utilize superior optical coupling technology, sigma-delta (sigma-delta) analog-to-digital converters, chopper-stabilized amplifiers, and fully differential circuit topologies to provide Unmatched isolation mode noise rejection, low offset, high gain accuracy and stability.
The ACPL-C87AT (±1% gain tolerance) and ACPL-C87BT (±0.5% gain tolerance) are designed for high precision DC voltage transmission in electronic motor drives, DC/DC and AC/DC converters, and battery monitoring systems sense. The ACPL-C87AT and ACPL-C87BT feature high input impedance and operate with analog input voltages up to 2.46 V full span. The shutdown function provides power saving and can be controlled from an external power source such as a microprocessor.
High Common Mode Transient Immunity (15kV/µs) The ACPL-C87AT and ACPL-C87BT maintain the precision and stability required to accurately monitor DC railways in high noise voltage motor control environments. This electrically safe barrier fluid is available in a compact, surface mount stretched SO-8 (SSO-8) package that meets global regulatory safety standards. Broadcom R2Coupler isolation products provide reinforced insulation and reliability required for critical automotive and high temperature industrial applications
