_______________General Desc ription
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 refer-
ence, forming a complete high-speed data acquisition
system.
All four converters include a built-in track/hold, eliminat-
ing 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.
Microprocessor interfaces 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 MX7824 and MX7828 are pin compatible with
Analog Devices’ AD7824 and AD7828. The MAX154
and MAX158, which feature internal references, are also
compatible with these products.
