Description

The ADC78H90 is a low-power, eight-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 eight input signals at inputs AIN1 through AIN8. The output serial data is straight binary, and is compatible with several standards, such as SPI™, QSPI™, MICROWIRE™, and many common DSP serial interfaces. The ADC78H90 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 to just 0.3 µW using a +3V supply, or 0.5 µW using a +5V supply. The ADC78H90 is packaged in a 16-lead TSSOP package. Operation over the industrial temperature range of −40°C to +85°C is ensured.
