Description
Microprocessor (µP) interfaces are simplified because the ADC can appear as a memory location or I/O port without external interface logic. The data outputs use latched, three-state buffer circuitry for direct connection to an 8-bit parallel µP data bus or system input port. The MAX113/MAX117 input/reference configuration enables ratiometric operation.
The 4-channel MAX113 is available in a 24-pin DIP or SSOP. The 8-channel MAX117 is available in a 28-pin DIP or SSOP. For +5V applications, refer to the MAX114/MAX118 data sheet.
