Expanded SARah family has 12 new dual-core ADCs for parallel sampling

Dresden, Germany -- – ZMDI has introduced 12 new members of its SARah converter family. The new A/D-converters ZADC510x and ZADC512x have a dual-core and operate with sampling rates of up to 1MSample/s.

The dual-core enables developers to make use of applications requiring the parallel sampling of 2 signals.

The ZMDI converter family, which operates on the principle of successive approximation (SAR) and has proven reliable in numerous applications, is ideally suited for use in high-speed applications, such as motion control, 3-phase motor control units, inverters or multi-axis positioning systems.

The A/D-converters ZADC510x and ZADC512x are available in 2-, 6-, and 10-channel versions.

With the dual-core ADCs developers can choose between models with 10- or 12-bits, as well as internal or external voltage references.

Additionally, the new ADCs offer variable alarm thresholds, 2-10 channels and operate within a temperature range of -25°C to +85°C.

As with all members of the SARah family, the new module series ZADC510x and ZADC512x are based on a scalable concept making them upwards and downwards compatible.

The standard pin-out of the converters and the software compatibility enable developers to quickly and simply design diverse variants of their systems, saving costs as well as time.

“The SARah family is well established in many market segments including industrial process control, power generation and white goods”, explained Bernhard Huber, ZMDI business line manager for standard components.

"SARah-ADCs enable higher device performance and improve efficiency, and with the new fast variants of the SARah family, developers can now fully exploit the benefits of these A/D-converters, such as low power consumption and compatibility of the individual models.“

The ZADC510x and ZADC512x offer high accuracy at very low power consumption. With sampling rates of up to 1MSample/s, the SARah family has a differential non-linearity (DNL) of ±1 LSB and an integral non-linearity (INL) of ±1 LSB over the temperature range of -25 to +85°C.

All SARah models have a serial interface that supports SPITM, QSPITM and MicrowireTM protocols – industry standards for ADCs.

Pricing and Availability

The SARah family's 10/12-bit dual-core ADCs for high-speed applications are sampling now and will be available in production volumes at the end of Q1/2010.

They will be offered in an SSOP package and suitable for operation at temperatures of -25 to +85°C.

Approximate unit prices range from Euro 2.00 to Euro 5.00 and US $2.80 to $7, depending on the model, based on unit quantities of 1,000.
