AD4130-8BCPZ-RL7

AD4130-8BCPZ-RL7 is a 32μA, ultra-low power, 24bit sigma-delta ADC with integrated PGA and FIFO. It is an ultra-low power, high precision, measurement solution for low bandwidth battery-operated applications. The fully integrated analogue front end (AFE) includes a multiplexer for upto 16 single-ended or eight differential inputs, programmable gain amplifier (PGA), 24-bit sigma-delta (Σ-Δ) analogue-to-digital converter (ADC), 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 (more than 5 years on a coin cell), that is, a first in, first out (FIFO) buffer and duty cycling. It is used in applications such as smart transmitters, wireless battery and harvester powered sensor nodes, portable instrumentation, temperature measurement: thermocouple, RTD, thermistors, pressure measurement: bridge transducers, healthcare and wearables.

• Current saving duty cycle ratio: 1/4 or 1/16, PGA with rail-to-rail analogue input
• 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
• Output data rate is 1.17SPS to 2.4KSPS, band gap reference with 15ppm/°C maximum drift
• Matched programmable excitation currents for RTDs, on-chip bias voltage generator for thermocouples
• Internal temperature sensor and oscillator, self and system calibration
• General-purpose outputs, diagnostic functionality, crosspoint multiplexed inputs
• 8 differential/16 pseudo differential inputs, 5MHz SPI (3-wire or 4-wire)
• Operating temperature range from -40°C to +125°C, package style is 32-lead LFCSP
