Description

Features

The ACPL-C87AT/C87BT isolation sensors utilize superior •ꢀ Unity Gain

optical coupling technology, with sigma-delta (S-D)

•ꢀ +/-0.5% (ACPL-C87BT) and +/-1% (ACPL-C87AT) Gain

analog-to-digital converter, chopper stabilized ampliﬁers,

and a fully diﬀerential circuit topology to provide

unequaled isolation-mode noise rejection, low oﬀset,

high gain accuracy and stability.

Tolerance @ 25° C

•ꢀ -0.3 mV Input Oﬀset Voltage

•ꢀ 0.05% Non Linearity

•ꢀ 25 ppm/°C Gain Drift vs. Temperature

•ꢀ 100 kHz Bandwidth

ACPL-C87AT ( 1% gain tolerance) and ACPL-C87BT

( 0.5% gain tolerance) are designed for high precision

DC voltage sensing in electronic motor drives, DC/DC

and AC/DC converter and battery monitoring system. The

ACPL-C87AT/C87BT features high input impedance and

operate with full span of analog input voltage up to 2.46 V.

The shutdown feature provides power saving and can be

controlled from external source, such as microprocessor.

•ꢀ 0 to 2 V Nominal Input Range

•ꢀ Qualiﬁed to AEC-Q100 Grade 1 Test Guidelines

•ꢀ Operating Temperature: -40° C to +125° C

•ꢀ Shutdown Feature (Active High)

•ꢀ 15 kV/ms Common-Mode Rejection at V = 1 kV

The high common-mode transient immunity (15 kV/ms)

of the ACPL-C87AT/C87BT maintains the precision and
