Glueless serial port interface to DSPs (TI TMS320Cxx, SPI, or standard DSPs)
Automatic cascading detection (ACD) makes cascade programming simple and allows up to 8 devices to
be connected in cascade.
On-fly reconfiguration modes include secondary-communication mode and direct-configuration mode (host
interface).
Continuous data-transfer mode for use with autobuffering (ABU) to reduce DSP interrupt service overhead
Event-monitor mode provides external-event control, such as RING/OFF-HOOK detection
Programmable ADC and DAC conversion rate
Programmable input and output gain control
Separate software control for ADC and DAC power-down
Analog (3-V to 5.5-V) supply operation
Digital (3-V to 5.5-V) supply operation
Power dissipation (P
D
) of 39 mWrms typical for 8-ksps at 3.3 V
Hardware power-down mode to 0.5 mW
Internal and external reference voltage (V
ref
)
Differential and single-ended analog input/output
2s-complement data format
Test mode, which includes digital loopback and analog loopback
600-ohm output driver
