DESCRIPTION

MAS6503 is a 24 bit Analog-to-Digital Converter

(ADC),

which

employs

a

delta-sigma

(ΔΣ)

conversion technique. The resolution for a signal

range of 373 mV is 17.4 bits.

MAS6503 is designed especially to meet

the requirement for low power consumption, thus

making it an ideal choice for battery powered

systems. Overall current consumption values of

18.3 µA (one conversion in a second at maximum

resolution) or less can be achieved. The minimum

supply voltage is as low as 1.8V.

MAS6503 has an on-chip decimator filter

that processes the output of the third order ΔΣ –

modulator, giving a high resolution conversion

result. The ADC also has four selectable input

signal ranges with eight optional offset levels.

A 4-wire SPI or 2-wire I2C bus compatible

serial bus is used for configuring conversion

parameters, starting a conversion and reading out

the A/D conversion result. The I2C address is

programmable to allow several sensors to be

connected to the same bus.

MAS6503 has one input channel suitable

for a piezoresistive pressure sensor. In addition to

pressure

measurement

the

device

can

be

configured for temperature measurement. The VDD

level monitoring feature is also useful especially in

battery operated systems.

The 256-bit EEPROM memory is available

for storing trimming and calibration data on chip. An

application optimized compensation algorithm can

be used

by the

host

system

for

optimal

performance.
