General Description
The MAX1098/MAX1099 implement both local and
remote temperature sensing with 10-bit resolution,
using +5V and +3V supply voltages, respectively.
Accuracy is ±1°C from 0°C to +70°C, with no calibra-
tion needed. The devices feature an algorithmic
switched-capacitor analog-to-digital converter (ADC),
on-chip clock, and 3-wire serial interface compatible
with SPI, QSPI, and MICROWIRE.
The MAX1098/MAX1099 also perform fully differential
voltage measurements with 10-bit resolution and sepa-
rate track-and-hold (T/N) 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 a floating common, or VDD/4 relative to
ground. An external reference may be used for more
accurate voltage measurements.
Typical power consumption is only 1.3mW (MAX1099).
A shutdown mode and two standby modes provide
multiple strategies for prolonging battery life in portable
applications that require limited sampling throughput.
The MAX1098/MAX1099 are available in 16-pin SSOP
packages.
