Safety and regulatory approvals  
Uꢀ recognition  
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 ±±00 mV  
(±ꢀ±0 mV full scale). The analog input is continuously sampled  
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 ꢀ V  
supply (VDD±).  
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. The AD7400A  
is offered in a 16-lead SOIC and 8-lead gull-wing surface mount  
DIP and has an operating temperature range of −40°C to  
+1±5°C.
