General Description
The MAX1298/MAX1299 implement local and remote
temperature sensing with 12-bit resolution, using +5V
and +3V supply voltages, respectively. Accuracy is
?癈 from 0 to +70癈, with no calibration needed. The
devices feature an algorithmic switched-capacitor ana-
log-to-digital converter (ADC), an on-chip clock, and a
3-wire serial interface compatible with SPI, QSPI", and
MICROWIRE
?/DIV>
.
The MAX1298/MAX1299 also perform fully differential
voltage measurements with 12-bit resolution and sepa-
rate track-and-hold (T/H) for positive and negative
inputs. Both devices accept versatile input modes con-
sisting of two 3-channel signal pairs, five 1-channel sig-
nals relative to an AIN5, or V
DD
/4 relative to ground. An
external reference may be used for more accurate volt-
age measurements.
Typical power consumption is only 1.3mW (MAX1299).
A shutdown mode and two standby modes provide
multiple strategies for prolonging battery life in portable
applications that require limited sampling throughput.
The MAX1298/MAX1299 are available in 16-pin SSOP
packages.
