AD7730BNZ
AD7730BNZ is a complete 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 modulator.

AD7789BRMZ
The AD7788/AD7789 are analogue front ends with minimal power and noise for low frequency measuring applications. The AD7789 has a low noise, 24-bit analog-to-digital converter (ADC) with one differential input. The AD7788 is the 16-bit counterpart of the AD7789. The gadgets run on an internal clock. As a result, the user is not required to give a clock source to the devices. The output data rate is 16.6 Hz, resulting in concurrent 50 Hz/60 Hz rejection. The devices are powered by a single 2.5 V to 5.25 V power source. The maximum power dissipation for the gadget when powered by a 3 V supply is 225 W. The AD7788/AD7789 are offered in a 10-lead MSOP configuration.

AD7801BRZ
1. Low Power, Single Supply operation. This part operates
from a single 2.7 V to 5.5 V supply and consumes typically
5 mW at 3 V, making it ideal for battery powered applications.
2. The on-chip output buffer amplifier allows the output of the
DAC to swing rail to rail with a settling time of typically 1.2 ?s.
3. Internal or external reference capability.
4. High speed parallel interface.
5. Power-down capability. When powered down the DAC
consumes less than 1 ?A at 25?C.
6. Packaged in 20-lead SOIC and TSSOP packages.
AD7805BR ANALOG DEVICE
AD7805BR? - Digital to Analog Converters - DAC QUAD 10-BIT PARALLEL DAC
The AD7804/AD7808 are quad/octal 10-bit digital-to-analog converters, with serial load capabilities, while the AD7805/AD7809 are quad/octal 10-bit digital-to-analog converters with parallel load capabilities. These parts operate from a 3.3 V to 5 V (?10%) power supply and incorporate an on-chip reference. These DACs provide output signals in the form of VBIAS ? SWING. SWING is derived internally from VBIAS. On-chip control registers include a system control register and channel control registers. The system control register has control over all DACs in the package. The channel control registers allow individual control of DACs.The complete transfer function of each individual DAC can be shifted around the VBIAS point using an on-chip Sub DAC. All DACs contain double-buffered data inputs, which allow all analog outputs to be simultaneously updated using the asynchronous LDAC input.
AD7824BQ
The AD7824 and AD7828 are high speed, multichannel, 8-bit
ADCs with a choice of four (AD7824) or eight (AD7828) multiplexed analog inputs. A half-flash conversion technique gives a fast
conversion rate of 2.5 ?s per channel, and the parts have a built-in
track-and-hold function capable of digitizing full-scale signals of
10 kHz (157 mV/?s slew rate) on all channels. The AD7824 and
AD7828 operate from a single 5 V supply and have an analog input
range of 0 V to 5 V, using an external 5 V reference.
Microprocessor interfacing of the parts is simple, using standard
Chip Select (CS) and Read (RD) signals to initiate the conversion
and read the data from the three-state data outputs. The half-flash
conversion technique means that there is no need to generate a
clock signal for the ADC. The AD7824 and AD7828 can be
interfaced easily to most popular microprocessors.
