AD4114BCPZ

AD4114 is a low power, low noise, 24bit, sigma-delta (Σ-Δ) analogue-to-digital converter (ADC) that integrates an analogue front end (AFE) for eight fully differential or 16 single-ended. Typical application includes programmable logic controller (PLC) and distributed control, system (DCS) modules and Instrumentation and measurement.

• Fast and flexible output rate: 1.25SPS to 31.25KSPS and channel scan data rate of 6.21KSPS/channel
• 17.3 noise free bits at 1007SPS per channel and 120dB CMRR of 50Hz and 60Hz at 20SPS per channel
• ±10V inputs, either 8 differential or 16 single-ended: VIN pin absolute maximum rating ±65V
• On-chip 2.5V reference: ±0.12% initial accuracy at 25°C, ±5ppm/°C (typical) drift
• Internal or external clock
• Power supplies: AVDD = 3V to 5.5V and IOVDD = 2 to 5.5V
• Total current consumption AVDD + IOVDD (IDD) = 3.9mA
• 3-or 4-wire serial digital interface (Schmitt trigger on SCLK) SPI, QSPI, MICROWIRE, DSP compatible
• 40 lead LFCSP package
• Operating temperature range from -40°C to +105°C
