LTC2367-16 16-Bit, 500ksps, Pseudo- Differential Unipolar SAR ADC with 94.7dB SNR
FEATURES DESCRIPTION
n
500ksps Throughput Rate
The LTC®2367-16 is a low noise, low power, high speed n
±0.75LSB INL (Max)
16-bit successive approximation register (SAR) ADC. n
Guaranteed 16-Bit No Missing Codes
Operating from a 2.5V supply, the LTC2367-16 has a 0V n
Low Power: 6.8mW at 500ksps, 6.8µW at 500sps
to VREF pseudo-differential unipolar input range with VREF n
94.7dB SNR (Typ) at fIN = 2kHz
ranging from 2.5V to 5.1V. The LTC2367-16 consumes n –
119dB THD (Typ) at fIN = 2kHz
only 6.8mW and achieves ±0.75LSB INL maximum, no n Guaranteed Operation to 125°C missing codes at 16 bits with 94.7dB SNR. n 2.5V Supply The LTC2367-16 has a high speed SPI-compatible serial n Pseudo-Differential Unipolar Input Range: 0V to VREF interface that supports 1.8V, 2.5V, 3.3V and 5V logic n VREF Input Range from 2.5V to 5.1V while also featuring a daisy-chain mode. The fast 500ksps n No Pipeline Delay, No Cycle Latency throughput with no cycle latency makes the LTC2367-16 n 1.8V to 5V I/O Voltages ideally suited for a wide variety of high speed applications. n SPI-Compatible Serial I/O with Daisy-Chain Mode An internal oscillator sets the conversion time, easing exter- n Internal Conversion Clock nal timing considerations. The LTC2367-16 automatically n 16-Lead MSOP and 4mm × 3mm DFN Packages powers down between conversions, leading to reduced power dissipation that scales with the sampling rate.
