TS8388B

2144C–BDC–04/03

A standard technique for reducing the amplitude of such errors down to ± 1 lsb consists of out-

putting the digital datas in Gray code format. Though the TS8388B has been designed for

featuring a Bit Error Rate of 10

-13 with a binary output format, it is possible for the user to

select between the Binary or Gray output data format, in order to reduce the amplitude of such

errors when occurring, by storing Gray output codes.

Digital Datas format selection:

•

BINARY output format if GORB is floating or V

CC.

•

GRAY output format if GORB is connected to ground (0V).

Diode Pin 49

One single pin is used for both DRRB input command and die junction monitoring. The pin

denomination is DRRB/DIOD. Temperature monitoring and Data Ready control by DRRB is

not possible simultaneously.

(See “Principle of Data Ready Signal Control by DRRB Input Command” on page 28 for Data

Ready Reset input command).

The operating die junction temperature must be kept below 145

°C, therefore an adequate

cooling system has to be set up. The diode mounted transistor measured Vbe value versus

junction temperature is given below.

ADC Gain Control

Pin 60

The ADC gain is adjustable by the means of the pin 60 (input impedance is 1 M

Ω in parallel

with 2 pF).

The gain adjust transfer function is given below.
