1.1 Purpose

The THS1030/31EVM evaluation module (EVM) provides a platform for

evaluation of the THS1030 and THS1031 10-bit analog-to-digital converters

(ADC) under various signal, reference, and supply conditions. Unless stated

explicitly, the functionality described in this user’s guide applies to both

THS1030 and THS1031 devices.

1.2 EVM Basic Functions

Analog input to the THS1030/31 is provided via an external SMA connector.

The input can be configured onboard to be ac, dc, or transformer coupled to

the input of the device.

An external SMA connector is provided on the THS1031 for the clamp input.

This allows external digital control of the ADC’s clamping function. The ADC

can be clamped to either the device reference or to ground via an onboard

jumper.

The EVM provides an external SMA connection for ADC clock input. This can

be configured to be either ac or dc coupled. Space is reserved on the board

for a crystal oscillator to perform this function, and can be populated when re-

quired.

In addition to the internal reference from the THS1030/31 device, options are

providedontheEVMtoallowadjustmentoftheADCreferenceviaanonboard

reference circuit.

Output from the EVM is via a 40-pin header connector. The digital lines from

the THS1030/31 are buffered using the SN74LVCC4245A before going to the

header.ThisallowstheTHS1030/31suppliestobevariedwithoutaffectingthe

output signal levels.

Power connections to the EVM are via 4-mm banana sockets. Separate input

connectors are provided for the analog and digital supply to the device, and

for the reference and output buffer circuits.

The THS1031 has a number of programmable registers that can be pro-

grammed using DIL switches on the EVM.

1.3 Power Requirements

TheEVMhas4dc-powersupplyconnections:5Vfortheoutputbuffers,2.7 V

to 5 V for the analog and digital supplies to the ADC, and 2.7 V to 5 V for the

referencecircuit.Eachofthesesuppliesisindependent,butitshouldbenoted
