LTC2315-12 12-Bit, 5Msps Serial Sampling ADC in TSOT
FEATURES DESCRIPTION
n
5Msps Throughput Rate
The LTC®2315-12 is a 12-bit, 5Msps, serial sampling A/D n
Guaranteed 12-Bit No Missing Codes
converter that draws only 6.4mA from a wide range analog n
Internal Reference: 2.048V/4.096V Span
supply adjustable from 2.7V to 5.25V. The LTC2315-12 n
Low Noise: 73dB SNR
contains an integrated bandgap and reference buffer which n
Low Power: 6.4mA at 5Msps and 5V
provide a low cost, high performance (20ppm/°C max) n
Dual Supply Range: 3V/5V operation
and space saving applications solution. The LTC2315-12 n Sleep Mode with < 1µA Typical Supply Current achieves outstanding AC performance of 72.6dB SINAD n Nap Mode with Quick Wake-up < 1 conversion and –84dB THD while sampling a 500kHz input frequency. n Separate 1.8V to 5V Digital I/O Supply The extremely high sample rate-to-power ratio makes the n High Speed SPI-Compatible Serial I/O LTC2315-12 ideal for compact, low power, high speed n Guaranteed Operation from –40°C to 125°C systems. The LTC2315-12 also provides both nap and n 8-Lead TSOT-23 Package sleep modes for further optimization of the device power within a system.
APPLICATIONS
The LTC2315-12 has a high-speed SPI-compatible serial n Communication Systems interface that supports 1.8V, 2.5V, 3V and 5V logic. The n High Speed Data Acquisition fast 5Msps throughput makes the LTC2315-12 ideally n Handheld Terminal Interface suited for a wide variety of high speed applications. n Medical Imaging
