描述
The ADC0820 is a high speed, microprocessor compatible, 8 bit analog-to-digital converter which uses a half-flash technique to achieve a conversion time of 1.4 μs. The converter has a 0V 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/μs.
The A/D easily interfaces with microprocessors by appearing as a memory location or I/O port without the need for external interfacing logic. Data outputs use latched, three-state buffer circuitry to allow direct connection to a microprocessor data bus or system I/O port. An over-flow output is also provided for cascading devices to achieve higher resolution.
Maxim's ADC0820 is pin-compatible with National Semiconductor's ADC0820 and provides improved specifications. It is packaged in 20-pin Small Outline, DIP and CERDIP packages.
