ANALOG DEVICES AD4698BCPZ Analogue to Digital Converter, 16 bit, 1 MSPS, Pseudo Differential, Serial, SPI, Single, 1.71 V

AD4698BCPZ is a compact, high accuracy, low power, 8-channel, 16bit, multiplexed input precision, successive approximation register (SAR) analogue-to-digital converter (ADC) with easy drive features and extensive digital functionality. It is optimal for use in space-constrained, multichannel, precision data acquisition systems and monitoring circuits. It features a true 16bit SAR ADC core with no missing codes, an 8-channel, low crosstalk multiplexer, a flexible channel sequencer, overvoltage protection clamp circuits on each analogue input, on-chip oversampling and decimation, threshold detection and alert indicators, and an autonomous conversion (autocycle) mode. Applications include photodiode monitoring, medical instrumentation, vital signs monitoring, electronic test and measurement, automated test equipment, instrumentation and process control, and battery-powered equipment.

• Reduced analogue input and reference drive requirements, guaranteed 16bit, no missing codes
• Easy drive features support system level designs with fewer components
• First conversion accurate, no latency or pipeline delay, customizable channel sequencer
• Fast conversion time and dual-/quad-SDO modes allow low SPI clock rates
• On-chip oversampling and decimation, threshold detection alerts, offset and gain correction
• Sample rate is 1Msps maximum at (AVDD = 2.7V to 5.5V, LDO-IN = 2.4V to 5.5V)
• Signal-to-noise ratio is 93dB typical at (VREF = 5V, fIN = 1KHz)
• Total harmonic distortion is -117dB typical at (VREF = 5V, fIN = 1KHz)
• 11.7MHz typical -3dB input bandwidth at (AVDD = 2.7V to 5.5V, LDO-IN = 2.4V to 5.5V)
• Operating temperature range from -40°C to +125°C, 24-lead LFCSP package
