APPLICATION INFORMATION
interface with host
Figure 34 shows examples of the interface between a single converter and a host DSP (TMS320C54x
DSP)
or microprocessor. The C54x is set as FWID = 1 (active pulse width = 1CLK), (R/X) DATDLY = 1 (1 bit data delay),
CLK(X/R)P = 0 (transmit data are clocked out at rising edge of CLK, receive data are sampled on falling edge
of CLK), and FS(X/R)P = 1 (FS is active high). If multiple converters connect to the same C54x, use CS as the
chip select.
The host microprocessor is set as the SPI master with CPOL = 0 (active high clock), and CPHA = 1 (transmit
data is clock out at rising edge of CLK, receive data are sampled at falling edge of CLK). 16 bits (or more) per
transfer is required.

sampling time analysis
Figure 35 shows the equivalent analog input circuit of the converter. During the sampling, the input capacitor,
Ci, has to be charged to VC, (VC = Vs ± voltage of 1/4 LSB = Vs ± [Vs/65532] for 14 bit converter).
t(s) = Rt × Ci × In (65532) where Rt = Rs+ri, t(s) = Sampling time
VI = Input Voltage at AIN
VS = External Driving Source Voltage
RS = Source Resistance
ri = Equivalent Resistor of Mux., 1.5 k
CI = Input Capacitance, 30 pF Max.
VC = Capacitance Charging Voltage
