Digilent 471-027 Ultimate Analog Discovery 2 Bundle Development Kit Signal Conversion Development Kit

The Digilent Analog Discovery 2™, developed in conjunction with Analog Devices®, is a multi-function instrument
that allows users to measure, visualize, generate, record, and control mixed signal circuits of all kinds. The low-cost
Analog Discovery 2 is small enough to fit in your pocket, but powerful enough to replace a stack of lab equipment,
providing engineering students, hobbyists, and electronics enthusiasts the freedom to work with analog and digital
circuits in virtually any environment, in or out of the lab. The analog and digital inputs and outputs can be
connected to a circuit using simple wire probes; alternatively, the Analog Discovery BNC Adapter and BNC probes
can be used to connect and utilize the inputs and outputs. Driven by the free WaveForms software, the Analog
Discovery 2 can be configured to work as any one of several traditional instruments, which include:

• Two-channel oscilloscope (1MΩ, ±25V, differential, 14- bit, 100Msample/sec, 30MHz+ bandwidth - with the Analog Discovery BNC Adapter Board)
• Two-channel arbitrary function generator (±5V, 14-bit, 100Msample/sec, 20MHz+ bandwidth - with the Analog Discovery BNC Adapter Board)
• Stereo audio amplifier to drive external headphones or speakers with replicated AWG signals
• 16-channel pattern generator (3.3V CMOS, 100Msample/sec)i ii
• 16-channel virtual digital I/O including buttons, switches, and LEDs – perfect for logic training applicationsiii iv
• 16-channel digital logic analyzer (3.3V CMOS, 100Msample/sec)v vi
• Two input/output digital trigger signals for linking multiple instruments (3.3V CMOS)vii
• Two programmable power supplies (0…+5V , 0…-5V. The maximum available output current and power depend on the Analog Discovery 2 powering choice:
• 250mW max for each supply or 500mW total when powered through USB
• 700mA max or 2.1W max for each supply when using an external wall power supply
• Single channel voltmeter (AC, DC, ±25V)
• Network analyzer – Bode, Nyquist, Nichols transfer diagrams of a circuit. Range: 1Hz to 10MHz
• Spectrum Analyzer – power spectrum and spectral measurements (noise floor, SFDR, SNR, THD, etc.)
• Digital Bus Analyzers (SPI, I²C, UART, Parallel)

The Blank Canvas provides a large prototyping surface for the Analog Discovery Studio and connections to the six power supplies (3.3V, 5V, ±12V, ± variable). The large prototyping surface has been wired in the configuration of two standard breadboards with 3 power rails for convenience. The connections to the power supplies are available as copper pads that can be soldered on directly, or the included power supply breadboard can be soldered on for a solderless connection. Eleven breakouts are provided at the top of the board for common IC package types. Two solderless breadboards can be optionally added to provide a solderless breadboard surface.
