MAX1299CEAE+
12-Bit Serial-Output Temperature Sensors with 5-Channel ADC
General Description
The MAX1298/MAX1299 implement local and remote
temperature sensing with 12-bit resolution, using +5V
and +3V supply voltages, respectively. Accuracy is
±1°C from 0 to +70°C, 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®.
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 VDD/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.

Note 1:Tested at VDD= +5.0V (MAX1298) and VDD= +3.0V (MAX1299).
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 4).
Note 7:Measured at VFS(+4.75V)- VFS(+5.25V)for the MAX1298 and at VFS(+2.7V)- VFS(+3.6V)for the MAX1299.
Note 8:External load should not change during conversions for specified accuracy.
Note 9:Excludes noise and self-heating effects. Output error for MAX129_C guaranteed by design.
Note 10:External temperature sensing over -40°C to +85°C range, device at +25°C. Guaranteed by design.
