AD4130-8BCBZ-RL7

AD4130-8 is an ultra low power, 24bit sigma-delta ADC with integrated PGA and FIFO. This is a high precision, measurement solution for low bandwidth battery operated applications. The fully integrated analogue front end includes a multiplexer for up to 16 single-ended or eight differential inputs, programmable gain amplifier, 24bit sigma-delta (Σ-Δ) analogue-to-digital converter, on-chip reference and oscillator, selectable filter options, smart sequencer, sensor biasing and excitation options, diagnostics, and newly added features to improve the battery-operated lifetime, that is, a first in, first out buffer and duty cycling. Application includes smart transmitters, wireless battery and harvester powered sensor nodes, portable instrumentation, temperature measurement: thermocouple, RTD, thermistors, pressure measurement: bridge transducers, healthcare and wearables.

• Smart sequencer and per channel configuration minimizes host processor load
• Deep embedded FIFO minimizes host processor load (depth of 256 samples)
• Autonomous FIFO interrupt functionality, threshold detection
• Single supply as low as 1.71V increasing battery length
• PGA with rail-to-rail analogue input
• Adaptable sensor interfacing functionality, matched programmable excitation currents for RTDs
• Output data rate range from 1.17 to 2400SPS (AVDD = 1.71V to 3.6V)
• Power supply rejection is 95dB (typ, AVDD = 1.71V to 3.6V, IOVDD = 1.65V to 3.6V)
• Turn on settling time is 280µs (typ, TA = 25°C, AVDD = 1.71V to 3.6V)
• 35 ball WLCSP package, temperature range from -40°C to +105°C
