MAX155BCPI+ (MAXIM INTEGRATED PRODUCTS)

The MAX155BCPI+ is an 8-channel ADC with simultaneous track/hold and reference in 28 pin DIP package. It is a high speed, 8bit, multichannel ADC with simultaneous track/hold (T/H) to eliminate timing differences between input channel samples. The MAX155 has an 8 analogue input channels. Each channel has its own T/H and all T/Hs sample at same instant. The MAX155 also feature 2.5V internal reference and power-down capability, providing a complete, sampling data acquisition system. When operating from a single +5V supply, the MAX155 perform either unipolar or bipolar, single ended or differential conversions. For applications requiring wider dynamic range or bipolar conversions around ground, VSS supply pin may be connected to -5V. Conversions are initiated with pulse to the write pin and data is accessed from the ADC's RAM with a pulse to read pin. A bidirectional interface updates the channel configuration and provides output data. The ADC may also be wired for output-only operation.
