ADC Single Semiflash 500ksps 8-bit Parallel 20-Pin PDIP N

The MAX150 is a high speed, microprocessor compatible, 8 bit analog to digital converter which uses a half-flash technique to achieve a conversion time of 1.34 ms. The converter has a OV to +5V analog input range and uses a single +5V supply. A built-in track-and-hold function is included, eliminating the need for an external track-and-hold for input slew rates up to 100mV/As. The MAX150 also provides an on-chip 2.5 V reference output, making it a complete analog to digital converter. The A/Ds easily interface with microprocessors by appearing as a memory location or I/O port without the need for external interfacing logic. The data outputs use latched, three-state buffer circuitry to allow direct connection to a microprocessor data bus or system input port. An over-flow output is also provided for cascading devices to achieve higher resolution. The MAX150 is also compatible with the MX7820 but also includes an internal 2.5V reference.
