Digital Logic Power (Input) – Digital core and input/output power supply. Nominally +3.3 V or +5.0 V.
Supply decoupling should placed as close as possible to pin 6.
VA
19
Analog Power (Input) - Analog power supply. Nominally +5.0 V.
GND

21
Ground (Input) - Ground reference for both analog and digital.
PSR_RESET
1
Reset (Input) - When PSR_RESET is low, the CS4461 enters a low power mode and all internal states
are reset. On initial power up, PSR_RESET must be held low until the power supply is stable, and all
input clocks are stable in frequency and phase.
VQ
22
Quiescent Voltage (Output) - Filter connection for the internal quiescent reference voltage.
REFGND
23
Reference Ground (Input) - Ground reference for the internal sampling circuits.
FILT+
24
Positive Voltage Reference (Output) - Positive reference voltage for the internal sampling circuit.
AIN+
AIN-
16
17
Differential PSR Analog Input (Input) - Signals are presented differentially to the delta-sigma modula-
tor via the AIN+/- pins.
PSR_MCLK
5
Master Clock (Input) - Clock source for the delta-sigma modulator and output data.
PSR_SYNC
3
Synchronization Data Output (Output) - Used to synchronize the serial data in the PWM modulator.
PSR_DATA
4
PSR Serial Data Output (Output) - Power supply modulated and formatted serial data.
PSR_EN
11
PSR Enable (Input) - A high to low transition on this pin will enable the PSR feedback circuit.
OVERFLOW
15
Overflow (Output, open drain) - Indicates a modulator overflow condition.
TEST
9
Test (Output) - This pin may toggle during normal operation and should be pulled low through a 47 k
resistor to GND in order to minimize noise.
