GENERAL DESCRIPTION
The AD7400A1 is a second-order, Σ-Δ modulator that converts
an analog input signal into a high speed, 1-bit data stream with
on-chip digital isolation based on Analog Devices, Inc., iCoupler
technology. The AD7400A operates from a 5 V power supply
and accepts a differential input signal of ±250 mV (±320 mV
full scale). The analog input is sampled continuously by the
analog modulator, eliminating the need for external sample-
and-hold circuitry. The input information is contained in the
output stream as a density of ones with a data rate of 10 MHz.
The original information can be reconstructed with an appropriate
digital filter. The serial I/O can use a 5 V or a 3 V supply (VDD2).
The serial interface is digitally isolated. High speed CMOS,
combined with monolithic air core transformer technology,
means the on-chip isolation provides outstanding performance
characteristics superior to alternatives such as optocoupler
devices. The part contains an on-chip reference and has an
operating temperature range of 40°C to +125°C. The AD7400A
is offered in a 16-lead SOIC package.
