Conversion Details
The LTC1606 uses a successive approximation algorithm
and an internal sample-and-hold circuit to convert an
analog signal to a 16-bit or two byte parallel output. The
ADC is complete with a precision reference and an internal
clock. The control logic provides easy interface to micro-
processors and DSPs. (Please refer to the Digital Interface
section for the data format.)
Conversion start is controlled by the CS and R/C inputs. At
the start of conversion, the successive approximation
register (SAR) is reset. Once a conversion cycle has
begun, it cannot be restarted.
During the conversion, the internal 16-bit capacitive DAC
output is sequenced by the SAR from the most significant
bit (MSB) to the least significant bit (LSB). Referring to
Figure 1, VIN is connected through the resistor divider to
the sample-and-hold capacitor during the acquire phase
and the comparator offset is nulled by the autozero switches.
In this acquire phase, a minimum delay of 1.5
s will
provide enough time for the sample-and-hold capacitor to
acquire the analog signal. During the convert phase, the
autozero switches open, putting the comparator into the
compare mode. The input switch switches CSAMPLE to
ground, injecting the analog input charge onto the sum-
ming junction. This input charge is successively com-
pared with the binary-weighted charges supplied by the
capacitive DAC. Bit decisions are made by the high speed
comparator. At the end of a conversion, the DAC output
balances the VIN input charge. The SAR contents (a 16-bit
data word) that represents the VIN are loaded into the
16-bit output latches.
Driving the Analog Inputs
The nominal input range for the LTC1606 is
±10V or
(
±4 VREF)andtheinputisovervoltageprotectedto±25V.
The input impedance is typically 10k
,therefore,itshould
be driven with a low impedance source. Wideband noise
coupling into the input can be minimized by placing a
1000pF capacitor at the input as shown in Figure 2. An
NPO-type capacitor gives the lowest distortion. Place the
