The AD9201 is a complete dual channel, 20 MSPS, 10-bit CMOS ADC. The AD9201 is optimized specifically for applications where close matching between two ADCs is required (e.g., I/Q channels in communications applications). The 20 MHz sampling rate and wide input bandwidth will cover both narrowband and spread-spectrum channels. The AD9201 integrates two 10-bit, 20 MSPS ADCs, two input buffer amplifiers, an internal voltage reference and multiplexed digital output buffers.
Each ADC incorporates a simultaneous sampling sample-and hold amplifier at its input. The analog inputs are buffered; no external input buffer op amp will be required in most applications. The ADCs are implemented using a multistage pipeline architecture that offers accurate performance and guarantees no missing codes. The outputs of the ADCs are ported to a multiplexed digital output buffer.
The AD9201 is manufactured on an advanced low cost CMOS process, operates from a single supply from 2.7 V to 5.5 V, and consumes 215 mW of power (on 3 V supply). The AD9201 input structure accepts either single-ended or differential signals, providing excellent dynamic performance up to and beyond its 10 MHz Nyquist input frequencies.
- Dual 10-Bit, 20 MSPS ADCs
A pair of high performance 20 MSPS ADCs that are optimized for spurious free dynamic performance are provided for encoding of I and Q or diversity channel information.
- Low Power
Complete CMOS Dual ADC function consumes a low 215 mW on a single supply (on 3 V supply). The AD9201 operates on supply voltages from 2.7 V to 5.5 V.
- On-Chip Voltage Reference
The AD9201 includes an on-chip compensated bandgap voltage reference pin programmable for 1 V or 2 V.
- On-chip analog input buffers eliminate the need for external op amps in most applications.
- Single 10-Bit Digital Output Bus
The AD9201 ADC outputs are interleaved onto a single output bus saving board space and digital pin count.
- Small Package
The AD9201 offers the complete integrated function in a compact 28-lead SSOP package.
- Product Family
The AD9201 dual ADC is pin compatible with a dual 8-bit ADC (AD9281) and has a companion dual DAC product, the AD9761 dual DAC.
