DESCRIPTION
The MS5541C is the miniature version of MS5535C pressure sensor module. It contains a precision piezoresistive pressure sensor and an improved version of the 16 Bit Micropower Sensor interface IC known from the MS5535C. Compared to the previous version the ESD sensitivity has been improved to 4kV on all pins. In addition to this the MS5541C is from its outer dimensions compatible to the MS54xx series of pressure sensors. It uses an antimagnetic polished stainless steel ring for sealing with O-ring. The sensor provides 16 Bit pressure and temperature data via a 3 wire serial interface that can be easily interfaced with 4 Bit low power microcontrollers. 64 Bit of factory programmed PROM provides calibration data for a highly accurate pressure and temperature calculation. The MS5541C is fully software compatible to the MS5535C and previous versions of MS5541.

DESCRIPTION
The ADS7884 is a 10-bit, 3-MSPS analog-to-digital converter (ADC), and the ADS7885 is a 8-bit, 3-MSPS ADC.
The devices include a capacitor based SAR A/D converter with inherent sample and hold.
The serial interface in each device is controlled by the CS and SCLK signals for glueless connections with microprocessors and DSPs.
The input signal is sampled with the falling edge of CS, and SCLK is used for conversion and serial data output.
The devices operate from a wide supply range from 2.7V to 5.5V.
The low power consumption of the devices make them suitable for battery-powered applications.
The devices also include a power saving powerdown feature for when the devices are operated at lower conversion speeds.
The high level of the digital input to the device is not limited to device VDD.
This means the digital input can go as high as 5.5V when device supply is 2.7V.
This feature is useful when digital signals are coming from other circuit with different supply levels.
Also this relaxes restriction on power up sequencing.
The ADS7884 and ADS7885 are available in a 6-pin SOT23 package and are specified for operation from –40°C to 125°C.
