DescripTion
The
LTC
®
2374-16
is a low noise, high speed, 8-channel
16-bit successive approximation register (SAR) ADC. Oper-
ating from a single 5V supply, the LTC2374-16 has a highly
configurable, low crosstalk 8-channel input multiplexer,
supporting fully differential, pseudo-differential unipolar
and pseudo-differential bipolar analog input ranges. The
LTC2374-16 achieves ±1LSB INL (maximum) in all input
ranges, no missing codes at 16-bits and 96dB (fully dif-
ferential)/ 93dB (pseudo-differential) SNR (typical).
The LTC2374-16 has an onboard low drift (20ppm/°C max)
2.048V temperature-compensated reference and a single-
shot capable reference buffer. The LTC2374-16 also has a
high speed SPI-compatible serial interface that supports
1.8V, 2.5V, 3.3V and 5V logic through which a sequencer
with a depth of 16 may be programmed. An internal os-
cillator sets the conversion time, easing external timing
considerations. The LTC2374-16 dissipates only 55mW
and automatically naps between conversions, leading to
reduced power dissipation that scales with the sampling
rate. A sleep mode is also provided to reduce the power
consumption of the LTC2374-16 to 300μW for further
power savings during inactive periods.
