Product Details
The LTC2315-12 is a 12-bit, 5Msps, serial sampling A/D converter that draws only 6.4mA from a wide range analog supply adjustable from 2.7V to 5.25V. The LTC2315-12 contains an integrated bandgap and reference buffer which provide a low cost, high performance (20ppm/°C max) and space saving applications solution. The LTC2315-12 achieves outstanding AC performance of 72.6dB SINAD and –84dB THD while sampling a 500kHz input frequency. The extremely high sample rate-to-power ratio makes the LTC2315-12 ideal for compact, low power, high speed systems. The LTC2315-12 also provides both nap and sleep modes for further optimization of the device power within a system.
The LTC2315-12 has a high-speed SPI-compatible serial interface that supports 1.8V, 2.5V, 3V and 5V logic. The fast 5Msps throughput makes the LTC2315-12 ideally suited for a wide variety of high speed applications.
