AD9245BCPZ-80 14-Bit 80 MSPS Pipelined ADC
The AD9245BCPZ-80 is a monolithic, single 3 V supply, 14-bit analog-to-digital converter (ADC) from Analog Devices, offering sampling rates of 20, 40, 65, and 80 MSPS with this specific variant operating at the maximum 80 MSPS. Fabricated on an advanced CMOS process, this device integrates a high-performance sample-and-hold amplifier (SHA) and an on-chip voltage reference, delivering exceptional dynamic performance with a signal-to-noise ratio (SNR) of 72.7 dBc and spurious-free dynamic range (SFDR) of 83.0 dBc at Nyquist input frequencies. The wide bandwidth, truly differential SHA provides 500 MHz input bandwidth and supports a variety of user-selectable input ranges and common modes, including single-ended operation, making it suitable for multiplexed systems switching full-scale voltage levels in successive channels as well as sampling single-channel inputs at frequencies well beyond the Nyquist rate.
Core Specifications
The AD9245 utilizes a multistage differential pipelined architecture with output error correction logic to deliver 14-bit accuracy and guarantee no missing codes over the full operating temperature range. Key DC performance specifications include differential nonlinearity (DNL) of ±0.5 LSB and integral nonlinearity (INL) of ±1.4 LSB. The ADC operates from a single 3 V power supply with a wide range of 2.7 V to 3.6 V for the analog section, while the digital output driver supply accommodates both 2.5 V and 3.3 V logic families for flexible system integration. Power consumption is remarkably low at 366 mW for the 80 MSPS variant, scaling down to 300 mW at 65 MSPS, 165 mW at 40 MSPS, and 90 mW at 20 MSPS, making it ideal for power-sensitive applications.
A single-ended clock input controls all internal conversion cycles, with a duty cycle stabilizer (DCS) compensating for wide variations in the clock duty cycle while maintaining excellent overall ADC performance. The device features a 12.5 ns clock period with a 4.2 ns output delay, supporting high-speed parallel data output. Digital output data is presented in either straight binary or twos complement formats, providing design flexibility for various processing backends.
Alternative low power ADCs
● AD9245BCPZ-65 – Same 14-bit resolution and 3 V supply in the identical 32-lead LFCSP package, operating at 65 MSPS with lower 300 mW power consumption for applications not requiring maximum sampling rate.
● AD9245BCPZ-40 – Lower-speed 40 MSPS variant offering the same 14-bit accuracy and pin compatibility, ideal for cost-sensitive designs where reduced sampling rate is acceptable.
● AD9245BCPZ-20 – The 20 MSPS entry-level member of the family, delivering the same performance specifications with minimal 90 mW power dissipation for ultra-low-power applications.
● AD9245BCPZRL7-80 – Identical electrical characteristics and packaging as the BCPZ-80, supplied in tape-and-reel packaging (1,500 units per reel) for high-volume automated assembly.
● AD9236BCPZ-80 – A pin-compatible 12-bit alternative offering the same 80 MSPS sampling rate and 3 V supply in the identical 32-LFCSP package, suitable when lower resolution is acceptable.
