Isolated Sigma-Delta Modulator  
Preliminary Technical Data  
AD7401A  
FEATURES  
GENERAꢀ DESCRIPTION  
20 MHz maximum external clock rate  
Second-order modulator  
16 bits no missing codes  
2 ꢀSB INꢀ typical at 16 bits  
3.5 µV/°C maximum offset drift  
On-board digital isolator  
The AD7401A1 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 AD7401A 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 up to  
±0 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±).  
On-board reference  
ꢀow power operation: 20 mA maximum at 5.25 V  
−40°C to +125°C operating range  
16-lead SOIC package  
AD7400A, internal clock version  
Safety and regulatory approvals  
Uꢀ recognition  
3750 V rms for 1 minute per Uꢀ 1577  
CSA Component Acceptance Notice #5A  
VDE Certificate of Conformity  
DIN EN 60747-5-2 (VDE 0884 Part 2): 2003-01  
DIN EN 60950 (VDE 0805): 2001-12; EN 60950: 2000  
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 AD7401A  
is offered in a 16-lead SOIC and has an operating temperature  
range of −40°C to +1±5°C.  
VIORM = 891 V peak
