The NTE2053 is a CMOS 8bit successive approximation Analog to Digital converter in a 20Lead DIP type package which uses a differential potentiometric ladder similar to the 256R products. This device is designed to allow operation with the NSC800 and INS8080A derivative control bus, and TRISTATER output latches directly drive the data bus. These A/Ds appear like memory locations or I/O ports to the microprocessor and no interfacing logic is needed. A new differential analog voltage input allows increasing the commonmode rejection and offsetting the analog zero input voltage value. In addition, the voltage reference input can be adjusted to allow encoding any similar analog voltage span to the full 8 bits of resolution. Features:
