FeaTures DescripTion
n
2Msps Throughput Rate
The LTC®2310-16 is a low noise, high speed 16-bit n
±3LSB INL (Typ), ±8LSB INL Guaranteed
successive approximation register (SAR) ADC with n
Guaranteed 16-Bit, No Missing Codes
differential inputs and wide input common mode range. n
8VP-P Differential Inputs with Wide Input Common
Operating from a single 3.3V or 5V supply, the LTC2310-16
Mode Range
has an 8VP-P differential input range, making it ideal for n
82dB SNR (Typ) at fIN = 500kHz
applications which require a wide dynamic range with n
–93dB THD (Typ) at fIN = 500kHz
high common mode rejection. The LTC2310-16 achieves n
No Cycle Latency
±3LSB INL typical, no missing codes at 16 bits and 82dB n Guaranteed Operation –40°C to 125°C SNR typical. n Single 3.3V or 5V Supply The LTC2310-16 has an onboard low drift (20ppm/°C max) n Low Drift (20ppm/°C Max) 2.048V or 4.096V Internal 2.048V or 4.096V temperature-compensated reference and Reference with 1.25V External Reference Input provides an external 1.25V buffered reference input. The n 1.8V to 2.5V I/O Voltages LTC2310-16 also has a high speed SPI-compatible serial n CMOS or LVDS SPI-Compatible Serial I/O interface that supports CMOS or LVDS. The fast 2Msps n Power Dissipation 35mW at VDD = 5V (Typ) throughput with no cycle latency makes the LTC2310-16 n Small 16-Lead (4mm × 5mm) MSOP Package ideally suited for a wide variety of high speed applications. The LTC2310-16 dissipates only 35mW with a 5V supply
