MAXIM MX7828KCAI

The MAX154/MAX158 and AD7824/AD7828 are high speed multi-channel A/D converters. The MAX154 and AD7824 have 4 analog input channels while the MAX158 and AD7828 have 8 channels. Conversion time for all devices is 2.5μs. The MAX154/MAX158 also features a 2.5V on-chip reference, forming a complete high speed data acquisition system. All converters include a built-in track-and-hold, eliminating the need for an external track-and-hold with many input signals. The analog input range is 0V to +5V although the A/D operates from a single +5V supply. Microprocessor interface's are simplified by the ADC's ability to appear as a memory location or I/O port without the need for external logic. The data outputs use latched, three-state buffer circuitry to allow direct connection to a microprocessor data bus or system input port. The AD7824 and AD7828 are pin compatible with Analog Devices' AD7824 and AD7828. The MAX154 and MAX158, which feature internal references, are also compatible with these products.
