1. HARDWARE

1.1 Introduction

The CDB5510/11/12/13 evaluation system pro-

vides

a

quick

means

of

testing

the

CS5510/11/12/13 Analog-to-Digital Converters

(ADCs). The CDB5510 evaluation board accepts

any of the four converters via an 8-pin SOIC sock-

et, and interfaces directly to a PC running though

an RS-232 serial interface.

The included analysis software allows the user to

control

the

various

functions

of

the

CS5510/11/12/13, as well as capture and save data.

The software also provides data analysis tools to

display the time domain, frequency domain, and

noise histogram performance for a captured set of

data.

1.2 Power Supply Options

The CS5510/11/12/13 ADCs are designed to oper-

ate from a supply voltage difference of 5 to 6 V be-

tween V+ and V-. The parts may be run from a

single 5 V supply, or any combination of voltages

that produce a 5 V span, such as +3 V and -2 V or

± 2.5 V. The CDB5510 evaluation board supports

both single and dual supply configurations. For a

single supply, both the V- and GND posts should

be connected to 0 V, and the V+ post should be

connected to the positive supply voltage. For dual

supply configurations, the GND post should be

connected to 0 V, the positive supply should be

connected to the V+ post, and the negative supply

should be connected to the V- post. Because the

RS-232 transceiver used on the board requires at

least 3 V for its supply voltage, it is recommended

that the V+ post always be at least 3 V for proper

operation of the evaluation board. If a different mi-

crocontroller is interfaced to the CS5510/11/12/13

through HDR6, other supply voltages may be used.

1.3 Analog Inputs

Analog input signals can be connected to the con-

verter’s inputs via the CDB5510’s AIN+ and AIN-

inputs (connector J3). Note that a simple RC net-

work filters the input to reduce broadband noise.

Both of the analog inputs can also be tied to the V-

supply by changing the position of HDR4 and

HDR5, or to the output of the amplifier section as

shown in Table 1. For a differential input the jump-

ers should be set to the “Direct Differential Input”

setting, and for a single-ended input on AIN+, the

jumpers should be set to the “Direct Single-Ended

Input” setting. The jumpers can also be set to con-

figure an amplifier input, if it is installed on the

evaluation board. The amplifier section of the

board is discussed in more detail in section 1.7.

1.4 Voltage Reference Options

The evaluation system provides three voltage refer-

ence options. The VREF pin can be connected to

the on-board 2.5V reference, to the positive supply

rail, or to an external voltage reference source via

HDR3, as shown in Table 2. When the HDR3

jumper on the CDB5510 is in the”V+” position, the

eval board’s supply voltage is selected. When this

jumper is in the “LT1019” position, the on-board

reference provides an absolute voltage level of 2.5

volts (the LT1019 was chosen for its low drift, typ-
