ZMD AG, a global supplier of analog and mixed-signal integrated circuits for demanding environments, will showcase analog-to-digital converters and signal conditioning devices at the Sensors Expo (www.sensorsexpo.com) on June 9 – 11. ZMD’s booth number is 820 at the Rosemont, Illinois, event. Attendees can evaluate the following devices for automotive, consumer, industrial and mobile medical applications:
MUlti-Sensor Interface Circuit (MUSic) family. The MUSic series offer multi-channel and multi-use sensor interfaces for microcontroller-based systems. Known for very high precision and ultra low power, these ICs are ideal for wearable medical instruments; sports and activity monitors that incorporate altimeters, barometers, navigation, and other tools; and industrial systems executing multiple sensor-based measurements such as flow monitors or scales.
The first device in the MUSic family, the ZMD21013, is a highly integrated smart-power architecture that offers programmable interfaces for up to three resistive bridge sensors. Through its high integration and its ultra-low-power standby-mode, the IC can reduce the average overall bill of materials as well as the overall power consumption of any multi-sensor-based system. The ZMD21013 connects through a SPI interface to a microcontroller or a digital signal processor (DSP).
ZMD31014 iLite Resistive Bridge Sensor Signal Conditioning IC. The highly integrated 31014 features built-in diagnostics, low-power standby mode, addressable I2C or SPI interface, and single-pass calibration procedure. The device is ideal for battery-powered applications such as desktop weather stations, medical pumps and meters, body watches and wireless transducers; and networked applications such as hospital beds and interactive toys.
The recently released new revision of the ZMD31014 iLite lets designers choose a modified gain factor up to 192 and a higher number of gain levels. The device also offers optional disabling of preamplifier nulling for bridge and temperature measurements in applications with very small preamp gain requirements. An additional filter prevents wake-up through unexpected system glitches.
Attendees will learn how to execute a single-pass calibration procedure using the ZMD31014 iLite development tools and experience the tools’ ease of use.
Successive-approximation (SAR) analog-to-digital converters (ADCs). The SARah family of 28 ADC devices offers upward and downward compatibility and a range of configuration options. Designers can choose from 8-, 10-, or 12-bit versions with internal or external voltage references and from 2-, 4-, or 8-channel versions and with or without internal voltage reference. Their common pin-out and software compatibility lets manufacturers easily vary system configurations such as . low, mid- and high-end versions.
SAR ADCs are widely used in industrial process control, power generation and consumer white goods applications, where they contribute to better appliance performance and greater energy efficiency.
