General Description
The MAX155/MAX156 are high-speed, 8-bit, multi-channel
analog-to-digital converters (ADCs) with simultaneous
track/holds (T/Hs) to eliminate timing differences between
input channel samples, The MAX155 has 8 analog input
channels, and the MAX156 has 4 analog input channels.
Each channel has its own T/H, and all T/Hs sample at the
same Instant. The ADC converts a channel in 36ys and stores
the result in an internal 8x8 RAM, The MAX155/MAX156 also
feature a 2.5V internal reference and power-down capability,
providing a complete, sampling data-acquisnlion system.
When operating from a single +5V supply, the
MAX155/MAX156 perform ether unipolar or Bipolar, single-
endec or differential conve'sions. For applications requiring
wider dynamic range or bipolar conversions around ground,
the vss supply p n may be connected to -5V
Conversions are initiated with a pulse to the W Trl, and
data is accessed from the ADC's RAM with a pulse to the
W pm A bidirectional interface updates the cnannel con-
figuration and prov'des output data. The ADC may also be
wired (oroutput-only operation The MAX155 comes in 28-pin
DIP and wide so oackages, and the MAX156 comes in
24-p'h narrow plasl C DIP and 28-pin Wide so packages,
