ZMD Launches Low-power ADCs for Automotive Real-time Applications
ZMD AG has announced that its SARah family of successive-approximation (SAR) analog-to-digital converters (ADC) now meets the rigorous requirements of the AEC-Q100 automotive industry standard. This qualification means the field-proven SARah family is now ready for automotive applications, saving designers and suppliers the cost and time needed to qualify a device after design-in.
Fujitsu Introduces Evaluation Kit for CHAIS ADC Technology
Fujitsu has announced an evaluation kit (BATBOARD) for its ultrafast ADC IP based on the revolutionary CHArge-mode Interleaved Sampler technology (CHAIS). The BATBOARD allows early silicon characterisation of a two-channel 56GSa/s 8-bit ADC using the single-chip ROBIN device (the first customer evaluation silicon for CHAIS technology) fabricated on Fujitsu’s standard 65nm CMOS technology.
16-Bit Industrial DAC with ±10V and 4-20mA Outputs from Maxim
Maxim has introduced the MAX5661 16-bit, industrial digital-to-analog converter (DAC) with two precision, high-voltage output circuits. This DAC features unprecedented integration by incorporating a voltage-output amplifier, current-output amplifier, and pass transistors on the same silicon.
TI claims smallest 16-bit DAC in tiny SC70 package
Texas Instruments has introduced the industry’s first single-channel digital-to-analog converter (DAC) family available in tiny SC70 packages.
