3-Channel, Low Noise, Low Power, 16-Bit, Sigma Delta ADC With On-Chip In-Amp

The AD7798 AD7799 are low power, low noise, complete Analog front ends for high precision measurement applications. The AD7798 AD7799 contains a low noise, 16-/24-bit - ADC with three differential Analog inputs. The on-chip, low noise Instrumentation Amplifier means that signals of small amplitude CAN be interfaced directly to the ADC With a gain setting of 64, the rms noise is 27 nV for the AD7799 and 40 nV for the AD7798 when the update rate equals 4.17 Hz.
On-chip features include a low-side power Switch reference detect, programmable digital output pins, burnout currents, and an internal Clock Oscillator The output data rate from the part is software-programmable and CAN be varied from 4.17 Hz to 470 Hz.
The part operates with a power supply from 2.7 V to 5.25 V. The AD7798 consumes a current of 300 A typical, whereas the AD7799 consumes 380 A typical. Both devices are housed in a 16-lead TSSOP package.
