ISOSD61
Datasheet 16-Bit isolated Σ-∆ modulator, single-ended and LVDS interfaces
Features
• Up to 25 MHz external clock input for easier synchronization • ±320 mV full scale analog input range • 16-bit resolution, no missing codes • 13-bit typical ENOB • 86 dB typical SNR • -83 dB typical THD • ±3 LSB typical INL • ±1 % maximum Gain Error • 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 • 6000 VPEAK Isolation Voltage VIOTM • 1200 VPEAK Working Voltage VIORM
Application
Current and voltage sensing in: • Industrial motor control • Solar inverter
Product status link
• UPS ISOSD61 • Electric vehicle charger
Product label
• Factory automation • Telecom and server power supply
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 ±320mV 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.
