Analog Devices Inc. (Norwood, MA) introduced the ADT7xxx family of temperature-to-digital converters that offer a combination of multi-channel analog-to-digital (ADC) converters and digital-to-analog converters (DAC) in addition to their core ambient and remote temperature measurement functions. The family of multi-channel temperature sensors is designed for applications such as PCs, communication systems, industrial instrumentation and portable equipment.
The new products are all SPI/I2C® compatible and feature a 10-bit digital ambient and remote temperature sensor. The ADT7411 adds an eight-channel ADC, the ADT7316/17/18 adds a quad-voltage output 12-/10-/8-bit DAC, and the ADT7516/17/18 adds a four-channel ADC and quad-voltage output 12-/10-/8-bit DAC. All are fully operational with 2.7V to 5.5V power supplies and over a temperature range from -55 to +125 degrees.
In 1,000-piece quantities, the ADT7411 is priced at $2.29 per unit; the ADT7316/17/18 are priced at $4.95, $2.95 and $1.75 per unit, respectively; and the ADT7516/17/18 are priced at $5.65, $3.65 and $2.65 per unit, respectively. Each is packaged in a tiny 16-lead QSOP package. All are sampling now with full production scheduled for fall 2002.
