STMicroelectronics ISOSD61

16-bit isolated Sigma-Delta modulator, single-ended and LVDS interfaces

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.

EVALST-ISOSD61T:

Evaluation board for ISOSD61 isolated sigma-delta converter

The EVALST-ISOSD61T is a full-featured evaluation board designed to allow the user to evaluate all the features of the ISOSD61 isolated analog-to-digital converter (ADC). The ISOSD61 device is a 1-bit sigma-delta modulator with an output buffer separated from the input interface circuitry by a galvanic isolation barrier. The isolation barrier provides galvanic isolation of up to 6000 VPEAK. When used in combination with a digital filter, the ISOSD61 device can be used to achieve 16-bit analog-to-digital (A/D) conversion with no missing codes.
