Housed in 32-pin DP packages, these converters feature laser trimming for accuracy and linearity surpassing the best modular competitive AD's. This series offers a unique combination of flexibility and simplicity which allows them to be used as stand-alone AD converters requiring no additional external potentiometers and needing only an analog input signal and encode command for operation. The AD features an accuracy of 0.012% and when combined with an HTC-0300 track-and-hold, forms an AD conversion system capable of up to 350kHz sampling rates. The HAS series AD's are ideally suited for applications requiring excellent performance characteristics, small size, low power consumption and adjustment-free operation. Some of these applications include radar, PCM, data-acquisition, and digital-signal-processing systems where FFT's and other digital processing techniques are to be performed on analog input data. +.V -GV +5V DGTAL ENCORE COMMAND AND 29.

Extreme care in circuit layout should be exercised when using these hybrids in order to obtain rated performance. n particular, input and outpu t runs should be as short as possible, a ground plane should be used to tie all ground pins together, and power supplies should be bypassed as close to the hybrid circuit power supply pins as possible. Do not allow input or other analog signal lines to be in close proximity to or cross over any digital output line. - TO-DGTALCOMLEBEBS YnL L 1.fb2l1
