Product overview

Description

The ISOSD61 is a galvanic isolated second order Sigma-Delta modulator based on embedded transformer coupling technology. It converts an analog input signal with maximum range of ±320 mV into a high speed, 25 Msps, 1-bit digital data stream. The signal information can be rebuilt by means of a digital filtering. The modulator is isolated from the digital I/O section through a high-speed isolated data coupling, whose performances are far better than other isolated transceivers like optocouplers.

All features
Up to 25 MHz external clock input

±320 mV full scale analog input range

16 bits resolution, no missing codes

86 dB typical SNR

-83 dB typical THD

13 bits typical ENOB

Low Voltage Differential Signaling (LVDS) and Single - ended (TTL/CMOS) options
–40°C to +125°C extended industrial temperature range

SO-16 wide package

30 kV/µs typical High Common-mode transient immunity

5000 V_PEAK Isolation Voltage V_IOTM

1700 V_PEAK Working Voltage V_IORM

Safety and Regulatory approvals:

IEC 60747-17 certified in SO16W package, File Number: 5022192-4880-0002/300335

UL1577 certified, File Number: E362869
