The ADC has a separate analog supply voltage pin, AVCC. A block diagram of the ADC is shown in Figure 107. The ADC contains a Sample and Hold circuit which ensures that the input voltage to theĪDC is held at a constant level during conversion.
If 200x gain is used, 7-bit resolution can be expected. If 1x or 10x gain is used, 8-bit resolution can be expected. Seven differential analog input channels share a common negative terminal (ADC1), while any other ADC input can be selected as the positive input terminal. Two of the differential inputs (ADC1, ADC0 and ADC3, ADC2) are equipped with a programmable gain stage, providing amplification steps of 0 dB (1x), 20 dB (10x), or 46 dB (200x) on the differential input voltage before the A/D conversion. The device also supports 16 differential voltage input combinations. The single-ended voltage inputs refer to 0 V (GND). The ADC is connected to an 8-channel Analog Multiplexer which allows 8 single-ended voltage inputs constructed from the pins of Port F. The ATmega128 features a 10-bit successive approximation ADC.

Follow the instructions that come with your Converter Box for how to tune analog channels.įor instructions on how to connect your converter box if it does not include an analog pass-through feature or for instructions on connecting your converter box to other components such as a VCR, go to or contact the FCC by calling 1-888-CALL-FCC (1-88) voice or 1-888-TELL-FCC (1-88) TTY. If your Converter Box includes an "analog pass-through" feature, this set up will also allow you to receive any stations that still broadcast in analog in your area. Using the remote that comes with your Converter Box, follow the on-screen set-up guide to scan for available DTV channels, and begin enjoying the benefits of Digital Television! Using the instructions that come with your Converter Box, tune your TV to channel 3 or 4. Step Plug the power cords on your Converter Box and TV into a power outlet, and turn on your TV and Converter Box.
Plug the other end into the “Antenna In (RF)” port on your TV. Step Using the coaxial wire that comes with your Converter Box, plug one end into the “Out To TV (RF)” port on the Converter Box.
Step Plug the existing coaxial wire into the “Antenna In (RF)” port on your Converter Box. Step Unplug the existing coaxial antenna wire from your TV “Antenna In (RF)” port. Before you begin the installation of the converter box, you should unplug your TV. Your new converter box will come with a coaxial wire and a remote control. Supplies: You will need your analog TV, the antenna you have been using (indoor or outdoor), and the coaxial wire that currently connects your antenna to your TV (as pictured on the right). This guide will help you prepare so that when you purchase a converter box you will know what to expect and whether you may need help setting it up. This guide describes the installation of a digital-to-analog converter box with your current antenna and analog TV.
