AD7828LP [Analog Devices]

The AD7824 and AD7828 are high-speed, multichannel 8-bit ADCs featuring 4 or 8 analog input channels with built-in track-and-hold function. They use a half-flash conversion technique for fast conversion rates of 2.5 µs per channel, enabling sampling frequencies of 100 kHz (AD7824) or 50 kHz (AD7828). These devices operate from a single 5 V supply with low power dissipation (typ. 40 mW) and offer tight total unadjusted error specifications (±1/2 LSB max). They include a simple digital interface using standard Chip Select (CS) and Read (RD) signals, eliminating the need for an external clock. The analog input range is 0 V to 5 V using an external 5 V reference, and they are fabricated in LC2MOS process for high performance.
