MAX1099CEAE
10-Bit Serial-Output Temperature Sensors with 5-Channel ADC
General DescriptionThe 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to

Note 2:Relative accuracy is the deviation of the analog value at any code from its theoretical value after the full-scale range has
been calibrated.
Note 3:Conversion time is defined as the number of clock cycles (64 for voltage measurements, 125 for temperature measure-
ments) multiplied by the internal clock period.
Note 4:Individual analog input voltages cannot extend beyond the power-supply rails.
Note 5:Input resistance is typically 250MΩ; 5µA limit reflects limitations in production testing.
Note 6:Specifications for full-on status assume continuous conversions. Power modes are software selected (Table 3).
Note 7:Measured at VFS(+4.75V)- VFS(+5.25V)for the MAX1098 and at VFS(+2.7V)- VFS(+3.6V)for the MAX1099.
Note 8:External load should not change during conversions for specified accuracy.
Note 9:Excludes noise and self-heating effects. Output error for MAX109_C guaranteed by design.
Note 10:External temperature sensing over -40°C to +85°C range, device at +25°C. Guaranteed by design.
