LTC2450

DESCRIPTION

Demonstration circuit 1067 features the LTC2450, a

16 bit high performance ΔΣ analog-to-digital con-

verter (ADC). The LTC2450 features 2LSB linearity,

2LSB offset, and 1.4µV RMS noise. The input is sin-

gle ended with a range of 0 (Ground) to Vcc. The

modulator’s proprietary sampling technique reduces

the average input current to less than 50nA – orders

of magnitude lower than typical delta sigma ADCs.

The LTC2450 is available in a 6 pin, 3x3mm DFN

package and has an easy to use SPI interface.

DC1067 is a member of Linear Technology‘s

QuickEval™ family of demonstration boards. It is de-

signed to allow easy evaluation of the LTC2450 and

may be connected directly to the target application’s

analog signals while using the DC590 USB Serial

Controller board and supplied software to measure

performance. The exposed ground planes allow

proper grounding to prototype circuitry. After evaluat-

ing with Linear Technology’s software, the digital sig-

nals can be connected to the end application’s proc-

essor / controller for development of the serial inter-

face.

Design files for this circuit board are available. Call

QUICK START PROCEDURE

Connect DC1067 to a DC590 USB Serial Controller

using the supplied 14 conductor ribbon cable. Con-

nect DC590 to host PC with a standard USB A/B ca-

ble. Run the evaluation software supplied with DC590

or downloaded from http://www.linear.com/software.

The correct program will be loaded automatically.

Click the COLLECT button to start reading the input

voltage. Details on software features are documented

in the control panel’s help menu.

Tools are available for logging data, changing refer-

ence voltage, changing the number of points in the

strip chart and histogram, and changing the number

of points averaged for the DVM display.

CONNECTION TO DC590 SERIAL CONTROLLER

J1 is the power and digital interface connector.

Connect to DC590 serial controller with supplied 14

conductor ribbon cable.

JUMPERS

JP1 – Select the source for REF+, either an LT6660-

5 or the regulated VCC voltage from the DC590

controller. Removing this jumper allows an external

supply to be connected to the VCC turret post.

ANALOG CONNECTIONS

Analog signal connections are made via the row of

turret posts along the edge of the board. Also, when

connecting the board to an existing circuit the ex-

posed ground planes along the edges of the board

may be used to form a solid connection between

grounds.

GND – Two ground turrets are connected directly to

the internal ground planes.

VCC – This is the supply and reference voltage for

the ADC. Do not draw any power from this point.

VIN – This is the single-ended input to the ADC.
