18-/16-Bit, 15Msps/10Msps/5Msps,
High Speed SAR ADCs
Description
Demonstration circuit 2290A features the LTC2387 family.
With up to 15Msps, these differential input, single channel,
18-/16-Bit, serial, high speed successive approximation
register (SAR) ADCs are available in a 32-Pin QFN package.
The LTC2387 family has an internal 20ppm/°C reference
and a serial LVDS interface. The following text refers to
the LTC2387 but applies to all members of the family, the
only difference being the sample rate and the number of
bits. The DC2290A demonstrates the AC performance of
the LTC2387 in conjunction with the DC718 data collection
board. Differential amplifier demo boards are available
separately that provide amplification of low level differ-
ential signals if required (see Table 2). Alternatively, by
connecting the DC2290A into a customer application the
performance of the LTC2387 can be evaluated directly in
that circuit.
