DESCRIPTION
The
LTC
®
2315-12
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.
