Rainbow Electronics MAX158 - Manual

_______________General Description
The MAX154/MAX158 are high-speed multi-channel
analog-to-digital converters (ADCs). The MAX154 has
four analog input channels while the MAX158 has eight
channels. Conversion time for both devices is 2.5µs.
The MAX154/MAX158 also feature a 2.5V on-chip refer-
ence, forming a complete high-speed data acquisition
system.
Both converters include a built-in track/hold, eliminating
the need for an external track/hold. 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.
