Product Details

ADC78H89CIMT 7-Channel 12-Bit A/D Converter

General Description

The ADC78H89 is a low-power, seven-channel CMOS 12-bit analog-to-digital converter with a conversion throughput of 500 KSPS. The converter is based on a successive-approximation register architecture with an internal track-and-hold circuit. It can be configured to accept up to seven input signals on pins AIN1 through AIN7.

The output serial data is straight binary, and is compatible with several standards, such as SPI™, QSPI™, MICROW-IRE™, and many common DSP serial interfaces.The ADC78H89 may be operated with independent analog and digital supplies. The analog supply (AVDD) can range from +2.7V to +5.25V, and the digital supply (DVDD) can range from +2.7V to AVDD. Normal power consumption using a +3V or +5V supply is 1.5 mW and 8.3 mW, respectively.

The power-down feature reduces the power consumption tojust 0.3 µW using a +3V supply, or 0.5 µW using a +5V supply. The ADC78H89 is packaged in a 16-lead TSSOP package. Operation over the industrial temperature range of −40˚C to +85˚C is guaranteed.
