AD7124-8BBCPZ-RL7

AD7124-8 is a low power, low noise, completely integrated analogue front end for high precision measurement applications. The device contains a low noise, 24bit Σ-Δ analogue-to-digital converter (ADC) and can be configured to have 8 differential inputs or 15 single-ended or pseudo differential inputs. One of the major advantages of the AD7124-8 is that it gives the user the flexibility to employ one of three integrated power modes. It features matched programmable excitation currents, internal clock oscillator, on-chip bias voltage generator, low-side power switch, general-purpose outputs, multiple filter options, internal temperature sensor, self and system calibration, sensor burnout detection, automatic channel sequencer, per channel configuration, independent interface power supply. Typical application includes temperature measurement, pressure measurement, industrial process control, instrumentation and smart transmitters.

• Power supply: 2.7V to 3.6V, ±1.8V and rail-to-rail analogue inputs for gains <gt/> 1
• RMS noise: low/mid/full power: 24/20/23nVrms at 1.17/2.34/9.4SPS, gain = 128 (255/355/930µA typ)
• Up to 22 noise free bits in all power modes (gain = 1)
• O/P data rate: full/mid/low power: 9.38 to 19,200SPS/2.34 to 4800SPS/1.17 to 2400SPS
• Simultaneous 50Hz/60Hz rejection at 25SPS (single cycle settling)
• Diagnostic functions (which aid safe integrity level (SIL) certification)
• Crosspoint multiplexed analogue inputs: 8 differential/15 pseudo differential inputs
• Programmable gain (1 to 128)
• 32 lead LFCSP package
• Operating temperature range from -40 to 125°C
