CH1/2 - Left/Right Input Channel Select, PIN 13.
Status at the end of a conversion cycle determines which analog input channel will be acquired
for the next conversion cycle. When in Free Run Mode, CH1/2 is an output, and will indicate
which channel is being sampled during the current acquisition phase.
SLEEP - Sleep, PIN 28.
When brought low causes the CS5101A or CS5102A to enter a power-down state. All
calibration coefficients are retained in memory, so no recalibration is needed after returning to
the normal operating mode. If using the internal crystal oscillator, time must be allowed after
SLEEP returns high for the crystal oscillator to stabilize. SLEEP should be tied high for normal
operation.
CODE - 2’s Complement/Binary Coding Select, PIN 16.
Determines whether output data appears in 2’s complement or binary format. If high, 2’s
complement; if low, binary.
BP/UP - Bipolar/Unipolar Input Range Select, PIN 17.
When low, the CS5101A or CS5102A accepts a unipolar input range from AGND to VREF.
When high, the CS5101A or CS5102A accepts bipolar inputs from -VREF to +VREF.
SCKMOD - Serial Clock Mode Select, PIN 27.
When high, the SCLK pin is an input; when low, it is an output. Used in conjunction with
OUTMOD to select one of 4 output modes described in Table 2.
OUTMOD - Output Mode Select, PIN 18.
The status of SCKMOD and OUTMOD determine which of four output modes is utilized. The
four modes are described in Table 2.
SCLK - Serial Clock, PIN 14.
Serial data changes status on a falling edge of this input, and is valid on a rising edge. When
SCKMOD is high SCLK acts as an input. When SCKMOD is low the CS5101A or CS5102A
generates its own serial clock at one-fourth the master clock frequency and SCLK is an output.
RST - Reset, PIN 2.
When taken low, all internal digital logic is reset. Upon returning high, a full calibration
sequence is initiated which takes 11,528,160 CLKIN cycles (CS5101A) or 2,882,040 CLKIN
cycles (CS5102A) to complete. During calibration, the HOLD input will be ignored. The
CS5101A or CS5102A must be reset at power-up for calibration, however; calibration is
maintained during SLEEP mode, and need not be repeated when resuming normal operation.
Analog Inputs
AIN1, AIN2 - Channel 1 and 2 Analog Inputs, PINS 19 and 24.
Analog input connections for the left and right input channels.
VREF - Voltage Reference, PIN 20.
The analog reference voltage which sets the analog input range. In unipolar mode VREF sets
full-scale; in bipolar mode its magnitude sets both positive and negative full-scale.
