AD7478ARTZ-REEL7

The AD7478ARTZ-REEL7 from Analog Devices is an 8-bit, high-speed, low-power successive approximation analog-to-digital converter (ADC). It features a throughput rate of up to 1 MSPS, making it suitable for applications requiring fast data conversion.

This ADC operates from a single power supply ranging from 2.7V to 5.25V. It includes a low-noise, wide bandwidth track-and-hold amplifier capable of handling input frequencies in excess of 6 MHz. The conversion process is controlled via a serial clock and chip select, allowing easy interfacing with microprocessors and DSPs using SPI or DSP compatible protocols.

With a typical power consumption of 3.6 mW at 1 MSPS with 3V supplies, the AD7478ARTZ-REEL7 is designed for power-sensitive applications. It also features a standby mode with a maximum current draw of 1 μA. The device is housed in a compact 6-lead SOT-23 package, suitable for surface mounting.

Key specifications include an 8-bit resolution, 1 MSPS sampling rate, and an input bandwidth of 6 MHz. The signal-to-noise ratio is 70 dB at a 100 kHz input frequency. The reference voltage is derived from the supply (VDD), allowing an analog input range from 0V to VDD.
