What are the key features of ADC14DS080CISQ?
- Dual-channel 14-bit ADC with 80 MSPS maximum sample rate and 0.0125 µs conversion time for high-speed data acquisition and communications applications
- Tight 1.4 V to 1.6 V differential analog input window with 0.0244% maximum linearity error enabling precise digitization of wideband IF signals
- Compact 60-pin LLP (9 mm x 9 mm, 0.5 mm pitch) package minimizing PCB footprint in high-density RF receiver and communications boards
What is ADC14DS080CISQ used for?
The ADC14DS080CISQ is designed for dual-channel wideband IF digitization in software-defined radio receivers, radar signal processors, and communications base station front-ends requiring 14-bit resolution at 80 MSPS per channel. Its two simultaneous channels support I/Q demodulation and diversity reception without additional ADCs, reducing system power and board complexity. High-speed instrumentation such as oscilloscope front-ends and spectrum analyzers also leverage this device for its combination of 14-bit dynamic range and sub-13 ns conversion speed.

Frequently Asked Questions
What is the maximum sample rate of the ADC14DS080CISQ and which signal bandwidths can it capture?
The ADC14DS080CISQ samples at up to 80 MSPS with a maximum conversion time of 0.0125 µs per sample. By the Nyquist theorem, it can accurately digitize analog input signals with bandwidths up to 40 MHz, making it suitable for IF capture in communications receivers and wideband radar front-ends operating in the HF through VHF frequency ranges.
What analog input voltage range does the ADC14DS080CISQ require and how does this affect front-end design?
The ADC14DS080CISQ requires a differential analog input voltage between 1.4 V and 1.6 V. Front-end designs must include a transformer balun or differential amplifier to convert single-ended IF signals to the required differential swing. Using a 1:1 transformer with a 50 ohm termination network is a common approach that preserves impedance matching at IF frequencies up to 40 MHz.
How many ADC channels does the ADC14DS080CISQ provide and can they sample simultaneously?
The ADC14DS080CISQ provides 2 analog input channels that sample simultaneously at up to 80 MSPS. Simultaneous dual-channel sampling is essential for I/Q signal demodulation in coherent receivers, where any timing skew between I and Q samples would introduce phase error and degrade EVM (error vector magnitude) performance.
What package does the ADC14DS080CISQ use and what are its key physical dimensions?
The ADC14DS080CISQ is packaged in a 60-pin LLP (leadless land package) measuring 9 mm x 9 mm with a 0.80 mm package height and 0.50 mm pin pitch. This compact footprint and the exposed thermal pad on the bottom help dissipate heat from high-speed ADC core operation, keeping junction temperature within spec at 80 MSPS continuous operation.
