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 V

/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.
