DescripTion
The
LTC
®
2312-12
is a 12-bit, 500ksps, serial sampling
A/D converter that draws only 3mA from a single 3V or
5V supply. The LTC2312-12 contains an integrated low
drift reference and reference buffer providing a low cost,
high performance (20ppm/°C maximum) and space sav-
ing solution. The LTC2312-12 achieves outstanding AC
performance of 72.7dB SINAD and –84dB THD while
sampling at 500ksps. The extremely high sample rate-to-
power ratio makes the LTC2312-12 ideal for compact, low
power, high speed systems. The supply current decreases
at lower sampling rates as the device automatically enters
nap mode after conversions.
The LTC2312-12 has a high speed SPI-compatible serial
interface that supports 1.8V, 2.5V, 3V and 5V logic. The
fast 500ksps throughput with no-cycle latency makes
the LTC2312-12 ideally suited for a wide variety of high
speed applications.
