Isolated Sigma-Delta Modulator  
Data Sheet  
AD7400A  
FEATURES  
GENERAL DESCRIPTION  
10 MHz clock rate  
Second-order modulator  
16 bits, no missing codes  
2 LSB INL typical at 16 bits  
1.5 µV/°C typical offset drift  
On-board digital isolator  
On-board reference  
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).  
250 mV analog input range  
Low power operation: 15.5 mA typical at 5.5 V  
−40°C to +125°C operating range  
16-lead SOIC package  
AD7401A, external clock version in 16-lead SOIC  
Safety and regulatory approvals  
UL recognition  
5000 V rms for 1 minute per UL 1577  
CSA Component Acceptance Notice #5A  
VDE Certificate of Conformity  
DIN V VDE V 0884-10 (VDE V 0884-10):2006-12  
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.
