GENERAL DESCRIPTION
The AD7730L is a complete low power analog front-end for
weigh-scale and pressure measurement applications. The device
accepts low level signals directly from a transducer and outputs
a serial digital word. The input signal is applied to a proprietary
programmable gain front end based around an analog modula-
tor. The modulator output is processed by a low pass program-
mable digital filter, allowing adjustment of filter cutoff, output
rate and settling-time.
The part features two buffered differential programmable gain
analog inputs as well as a differential reference input. The part
operates from a single +5 V supply and typically consumes less
than 3 mA. It accepts four unipolar analog input ranges: 0 mV
to +10 mV, +20 mV, +40 mV and +80 mV and four bipolar
ranges
±10 mV, ±20 mV, ±40 mV and ±80 mV. The peak-to-
peak resolution achievable directly from the part is 1 in 110,000
counts. An on-chip 6-bit DAC allows the removal of TARE
voltages. Clock signals for synchronizing ac excitation of the
bridge are also provided.
The serial interface on the part can be configured for three-wire
operation and is compatible with microcontrollers and digital
signal processors. The AD7730L contains self-calibration and
system calibration options and features an offset drift of less
than 5 nV/
°C and a gain drift of less than 3 ppm/°C.
The part is available in a 24-lead SOIC and 24-lead TSSOP
package.
