DESCRIPTION
SFOR
1
TTL level input; in normal mode this input selects the serial interface output format; output
format is selected as follows:
SFOR = HIGH selects Format 1
SFOR = LOW selects Format 2 (similar to I
2
S)
schmitt-trigger input; in normal mode, this input is used to select standby mode:
STDB = HIGH selects normal operation
STDB = LOW selects standby mode (low power consumption)
TTL level output; in normal mode this output indicates whether the internal digital signal is
within 1 dB of maximum; if so, the output will go HIGH for 131072 clock cycles (approximately
11 ms); in standby mode this output is forced LOW
CMOS level input; system clock input; nominally clocked at 256f
s
digital supply voltage (4.5 to 5.5 V)
digital ground
TTL level output (3-state); in normal mode this pin outputs data from the serial interface; in
standby mode, this output is high impedance
TTL level input/output; serial interface word select signal; in master mode (SLAVE = LOW),
this pin outputs the serial interface word select signal; in slave mode (SLAVE = HIGH), this pin
is the word select input to the serial interface; in standby mode (STDB = LOW) this pin is
always an input (high impedance); for polarity: see Table 1
TTL level input/output; in master mode (SLAVE = LOW) the pin outputs the serial interface bit
clock; in slave mode (SLAVE = HIGH) this pin is the input for the external bit clock; data on
SDO is clocked out on the HIGH-to-LOW transition of SCK; the data is valid on the
LOW-to-HIGH transition
Test 1; TTL level input with internal pull-down; in slave mode (slave = HIGH), this pin is used
to select extra serial interface formats (see Table 2)
TTL level input; this input is used to enable the internal high-pass filter when HIGH; in
scan-test mode (TESTB = LOW and TEST1 = LOW) this pin functions as ‘scan chain c’ input
Test B; CMOS level input with internal pull-up; in normal applications, this input should be left
HIGH
analog ground; this pin is internally connected to V
