the digital lines should be buffered from the device by
logic gates as shown in Figure 6.
Shutdown Mode
The MAX260/MAX261/MAX262 enters a shutdown/
standby mode when all zeroes are written to the Q
addresses of filter A (Q0A–Q6A). When shut down,
power consumption with ±5V supplies typically drops
to 10mW. When reactivating the filter after shutdown,
allow 2ms to return to full operation.
Filter Operating Modes
There are several ways in which the summing amplifier
and integrators in each MAX260/MAX261/MAX262 filter
section can be configured. The four most versatile
interconnections (modes) are selected by writing to
inputs M0 and M1 (see Tables 4 and 5). These modes
use no external components. A fifth mode, 3A, makes
use of an additional op amp (included in the MAX261
and MAX262) and external resistors, but uses the same
internal configuration and is selected with the same
programming code, as mode 3.
