LTC2380-24/LTC2368-24:

24-Bit, 2Msps/1Msps, Low Power,

SAR ADCs with Digital Filter

DESCRIPTION

The LTC^®2380-24 and LTC2368-24 are low power, low

noise, high speed, 24-bit SAR ADCs with an integrated

digital averaging filter that operates from a single 2.5V

supply. The following text refers to the LTC2380-24 but

appliestobothparts.TheLTC2380-24hasfullydifferential

inputs and samples at 2Msps, while the LTC2368-24 has

pseudo-differential inputs and samples at 1Msps. The

LTC2380-24has–117dBTHD, consumesonly28mWand

achieves 3.5ppm INL max with no missing codes at 24

bits. The DC2289A demonstrates the DC and AC perfor-

mance of the LTC2380-24 in conjunction with the DC590

orDC2026QuikEval™andDC890PScope™datacollection

boards. Use the DC590 or DC2026 to demonstrate DC

performance such as peak-to-peak noise and DC linearity.

Use the DC890 if precise sampling rates are required or to

demonstrate AC performance such as SNR, THD, SINAD

and SFDR. The Demonstration Circuit 2289A is intended

to showrecommendedgrounding, componentplacement

and selection, routing and bypassing for this ADC.

Design files for this circuit board including the

schematic, BOM and layout are available at

http://www.linear.com/demo/DC2289A or scan the QR

code on the back of the board.
