AMC1203
SBAS427C – FEBRUARY 2008 – REVISED JUNE 2011 www.ti.com 1-Bit, 10MHz, 2nd-Order, Isolated Delta-Sigma Modulator
Check for Samples: AMC1203 FEATURES DESCRIPTION The AMC1203 is a 1-bit, 10MHz, isolated delta-sigma
(О”ОЈ) modulator with an output buffer separated from
the input interface circuitry by a silicon dioxide (SiO2)
isolation barrier. This barrier provides galvanic
isolation of up to 4000VPEAK. Used in conjunction with
isolated power supplies, these devices prevent noise
currents on a data bus or other circuits from entering
the local ground and interfering with or damaging
sensitive circuitry. 1 2 16-Bit Resolution
