DESCRIPTION
The
LTC
®
2512-24
is a low noise, low power, high-perfor-
mance 24-bit ADC with an integrated configurable digital
filter. Operating from a single 2.5V supply, the LTC2512-
24 features a fully differential input range up to ±V
REF
,
with V
REF
ranging from 2.5V to 5.1V. The LTC2512-24
supports a wide common mode range from 0V to V
REF
simplifying analog signal conditioning requirements.
The LTC2512-24 simultaneously provides two output
codes: (1) a 24-bit digitally filtered high precision low
noise code, and (2) a 22-bit no latency composite code.
The configurable digital filter reduces measurement noise
by lowpass filtering and down-sampling the stream of
data from the SAR ADC core, giving the 24-bit filtered
output code. The 22-bit composite code consists of a
14-bit code representing the differential voltage and an
8-bit code representing the common mode voltage. The
22-bit composite code is available each conversion cycle,
with no cycle of latency.
The digital filter can be easily configured for 4 different
down-sampling factors by pin strapping. The configura-
tions provide a dynamic range of 108dB at 400ksps and
117dB at 50ksps. The digital lowpass filter relaxes the
requirements for analog anti-aliasing. Multiple LTC2512-
24 devices can be easily synchronized using the SYNC pin.
