Output-Data Format
Figures 6–9 illustrate the conversion timing for the
MAX1020/MAX1022/MAX1057/MAX1058. All 10-bit con-
version results are output in 2-byte format, MSB first,
with four leading zeros and with the LSB followed by 2
sub-bits. Data appears on DOUT on the falling edges of
SCLK. Data is binary for unipolar mode and two’s com-
plement for bipolar mode and temperature results. See
Figures 3, 4, and 5 for input/output and temperature-
transfer functions.
ADC Transfer Functions
Figure 3 shows the unipolar transfer function for single-
ended or differential inputs. Figure 4 shows the bipolar
transfer function for differential inputs. Code transitions
occur halfway between successive-integer LSB values.
Output coding is binary, with 1 LSB = VREF1 / 1024
(MAX1057) and 1 LSB = VREF1 / 1024 (MAX1020/
MAX1022/MAX1058) for unipolar and bipolar operation,
and 1 LSB = +0.125°C for temperature measurements.
Bipolar true-differential results and temperature-sensor
results are available in two’s complement format, while
all others are in binary. See Tables 6, 7, and 8 for
details on which setting (unipolar or bipolar) takes
precedence.
In unipolar mode, AIN+ can exceed AIN- by up to
VREF1. In bipolar mode, either input can exceed the
other by up to VREF1 / 2.
