The LTC2389-16 is a low noise, high speed 16-bit successive approximation register (SAR) ADC. Operating from a single 5V supply, the LTC2389-16 supports pinconfigurable fully differential (±4.096V), pseudo-differential unipolar (0V to 4.096V), and pseudo-differential bipolar (±2.048V) analog input ranges, allowing it to interface with multiple signal chain formats without requiring additional level translation or signal conditioning. The LTC2389-16 achieves ±1LSB INL (maximum), no missing codes at 16-bits, and 96.0dB (fully differential)/ 93.5dB (pseudo differential) SNR (typical).The LTC2389-16 includes a precision internal 4.096V reference, with a guaranteed 0.5% initial accuracy and a ±20ppm/°C (maximum) temperature coefficient, as well as an internal reference buffer. Fast 2.5Msps throughput with no cycle latency in the parallel interface modes makes the LTC2389-16 ideally suited for a wide variety of high speed applications. An internal oscillator sets the conversion time, easing external timing considerations. The LTC2389-16 dissipates only 162.5mW at 2.5Msps, while both nap and sleep power-down modes are provided to further reduce power consumption during inactive periods.ApplicationsMedical ImagingHigh Speed, Wide Dynamic Range Data AcquisitionIndustrial Process ControlInstrumentationATE
