MAS6502 Datasheet PDF - Micro Analog systems

DESCRIPTION
MAS6502 is a 16 bit Analog-to-Digital Converter (ADC), which employs a delta-sigma (∆Σ) conversion technique. With the linear input signal range of 260 mVPP the linearity is 14 bits.
MAS6502 is designed especially to meet the requirement for low power consumption, thus making it an ideal choice for battery powered systems. The MAS6502 is equipped with a standby function, i.e. the ADC is in power down between each conversion. By utilizing this and overall low power consumption, current consumption values of 2.5 µA (one pressure conversion in a second with full 14-bit accuracy) or less can be achieved.
