ANALOG DEVICES AD4697BCPZ Analogue to Digital Converter, 16 bit, 500 kSPS, Pseudo Differential, SPI, Single, 2.7 V

AD4697BCPZ is a compact, high accuracy, low power, 8-channel, 16bit, 500kSPS, multiplexed input precision, successive approximation register (SAR) analogue-to-digital converter (ADC) with easy drive features and extensive digital functionality. The AD4697 is optimal for use in space constrained, multichannel, precision data acquisition systems and monitoring circuits. The AD4697 feature 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, battery-powered equipment.

• Guaranteed 16bit, no missing codes, first conversion accurate, no latency or pipeline delay
• Easy drive features support system level designs with fewer components
• Fast conversion time and dual-/quad-SDO modes allow low SPI clock rates
• Customizable channel sequencer, on-chip oversampling and decimation
• Threshold detection alerts, offset and gain correction, autonomous conversion (autocycle) mode
• 1.14V to 1.98V logic SPI, internal LDO enables 2.7V to 5.5V, single analogue supply operation
• Sample rate is 500kSPS maximum at (TA = -40°C to +125°C)
• CMRR is 69.5dB typical at (fIN = 250KHz, IN? = COM, odd numbered input)
• Integral nonlinearity error is ±0.4LSB typical at (TA = -40°C to +125°C)
• Temperature range from -40°C to +125°C, 24-lead LFCSP package
