General Description

The MAX154/MAX158 and MX7824/MX7828 are high speed, multi-channel analog-to-digital converters (ADCs). The MAX154 and MX7824 have four analog input channels, while the MAX158 and MX7828 have eight channels. Conversion time for all devices is 2.5µs. The MAX154/MAX158 also feature a 2.5V on-chip reference, forming a complete high-speed data acquisition system.

All four converters include a built-in track/hold, eliminating the need for an external track/hold with many input signals. The analog input range is 0V to +5V, although the ADC operates from a single +5V supply.
