Analog Devices Inc. AD7791BRMZ-REEL
- Part Number:
- AD7791BRMZ-REEL
- Manufacturer:
- Analog Devices Inc.
- Ventron No:
- 3007737-AD7791BRMZ-REEL
- Description:
- IC ADC 24BIT SIGMA-DELTA 10MSOP
- Datasheet:
- AD7791BRMZ-REEL
Description
The AD7791 is a low-power, complete analog front end for low-frequency measurement applications. It features a low-noise 24-bit Σ-Δ ADC with one differential input that can be buffered or unbuffered. The device operates from an internal clock, eliminating the need for an external clock source. The output data rate is software programmable from 9.5 Hz to 120 Hz, with an rms noise of 1.1 μV at the lower update rate. The internal clock frequency can be divided by a factor of 2, 4, or 8, reducing current consumption. The update rate, cutoff frequency, and settling time scale with the clock frequency.
The AD7791 operates with a power supply from 2.5 V to 5.25 V. When operating from a 3 V supply, the power dissipation is 225 pW maximum. It is housed in a 10-lead MSOP.
Features
Low power consumption: 75 μA max (normal), 1 μA max (power-down)
RMS noise: 1.1 μV at 9.5 Hz update rate
19.5-bit p-p resolution (22 bits effective resolution)
Integral nonlinearity: 3.5 ppm typical
Simultaneous 50 Hz and 60 Hz rejection
Internal clock oscillator
Rail-to-rail input buffer
Voo monitor channel
Temperature range: -40°C to 105°C
Applications
Smart transmitters
Battery applications
Portable instrumentation
Sensor measurement
Temperature measurement
Pressure measurement
Weigh scales
4 to 20 mA loops
