'the ads1130 is a precision, 18-bit analog-to-digital converter (adc). with an onboard low-noise gain amplifier, onboard oscillator, and precision 18-bit delta-sigma adc, the ads1130 provides a complete front-end solution for bridge sensor applications including weigh scales and strain gauges.
the low-noise amplifier has a gain of 64, supporting a full-scale differential input of ±39mv. the delta-sigma adc has 18-bit effective resolution and is comprised of a third-order modulator and fourth-order digital filter. two data rates are supported: 10sps (with both 50hz and 60hz rejection) and 80sps. the ads1130 can be put into a low-power standby mode or shut off completely in power-down mode.
all of the features of the ads1130 are controlled by dedicated pins; there are no digital registers to program. data are output over an easily-isolated serial interface that connects directly to the msp430 and other microcontrollers.
the ads1130 is available in a tssop-16 package and is specified for operation from -40°c to +85°c.
