Product details
Overview
LTC2207CUK#PBF from Analog Devices (formerly Linear Technology) is a 16-bit, 105Msps high-speed analog-to-digital converter optimized for digitizing wide dynamic range signals up to 700MHz full-power bandwidth. It features a programmable gain amplifier (PGA), 78.2dBFS noise floor, 100dB spurious-free dynamic range (SFDR), and ultralow 80fsRMS aperture jitter - enabling undersampling in cellular base station receivers and spectrum analyzers.
For engineers reviewing the LTC2207CUK#PBF datasheet, LTC2207CUK#PBF pinout, LTC2207CUK#PBF application, or LTC2207CUK#PBF equivalent, key selection criteria include its differential clock interface, 48-pin 7mm × 7mm QFN package, 3.3V analog supply with independent 0.5–3.6V digital output voltage control, and support for dithering and output randomization to suppress harmonic artifacts in RF sampling systems.
Technical Context
The LTC2207CUK#PBF implements a 16-bit pipelined ADC architecture with integrated sample-and-hold, internal reference generator, and correction logic. Its PGA front end supports two input ranges (2.25VP-P at gain = 1, 1.5VP-P at gain = 1.5), and the ENC+/ENC– differential clock interface accepts sine wave, PECL, LVDS, TTL, or CMOS inputs.
It includes optional clock duty cycle stabilization, internal dither, and data output randomization. The device delivers ±4LSB integral nonlinearity and ±1LSB differential nonlinearity over temperature, with DC-coupled analog inputs and 2's complement or offset binary output formatting selectable via the MODE pin.

Key Features
| Feature | Design Value |
|---|---|
| Programmable Gain Amplifier (PGA) | Selects between 2.25VP-P (gain = 1) and 1.5VP-P (gain = 1.5) input ranges to optimize SNR for varying signal amplitudes. |
| Internal Dither | Reduces harmonic distortion and improves SFDR by adding controlled noise to the ADC core, especially beneficial for low-level periodic signals. |
| Output Randomization | XOR-based scrambling of D1–D15 with D0 reduces deterministic digital switching noise coupling into analog sections. |
| Separate OVDD Supply | Enables interfacing with 1.8V, 2.5V, or 3.3V logic families without level-shifting, simplifying FPGA/ASIC integration. |
| Out-of-Range Indicator (OF) | Digital flag signaling overrange or underrange condition, allowing real-time signal clipping detection and AGC feedback. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9268BCPZ-105 | 16-bit, 105Msps; JESD204B serial output; higher power (1.2W); no integrated PGA. | Requires FPGA with JESD204B receiver; better suited for space-constrained, high-channel-count systems. | Choose AD9268BCPZ-105 when serial interface and lower pin count outweigh need for PGA and parallel CMOS outputs. |
| LTC2206CUK#PBF | Same family, pin-compatible; 80Msps sample rate; 725mW power; identical PGA, dither, and package. | Lower sample rate trades bandwidth for reduced power and thermal load in cost-sensitive or thermally constrained designs. | Choose LTC2206CUK#PBF when 80Msps meets system Nyquist requirements and lower power dissipation is prioritized. |
Compared with LTC2207CUK#PBF, the AD9268BCPZ-105 offers serial interface scalability but sacrifices analog flexibility and adds FPGA complexity, while the LTC2206CUK#PBF provides identical feature set at reduced speed and power - making it a drop-in alternative where 105Msps is not required.

FAQ
What is the maximum analog input frequency supported by the LTC2207CUK#PBF?
The LTC2207CUK#PBF supports a full-power analog input bandwidth of 700MHz, meaning it can accurately digitize signals up to that frequency without significant amplitude roll-off. This enables direct RF sampling applications such as cellular base station IF stages and spectrum analyzer front ends, provided the input signal remains within the specified 1.5VP-P or 2.25VP-P differential range and common-mode voltage constraints.
Does the LTC2207CUK#PBF require an external reference voltage?
No, the LTC2207CUK#PBF includes an internal 2.5V bandgap reference. The SENSE pin determines reference selection: tying SENSE to VDD activates the internal reference, while applying 2.5V or 1.25V externally enables external reference operation. Both configurations yield a full-scale ADC range of 2.25VP-P when PGA = 0, ensuring consistent scaling regardless of reference source.
How does the PGA function affect the LTC2207CUK#PBF's input range and noise performance?
The PGA in the LTC2207CUK#PBF configures two input ranges: PGA = low gives 2.25VP-P (gain = 1), PGA = high gives 1.5VP-P (gain = 1.5). Higher gain improves SNR for small signals by amplifying them before quantization, but reduces headroom. The datasheet confirms SNR remains ≥75.5dBFS across both settings at 5MHz, confirming effective noise optimization across operating modes.
Can the LTC2207CUK#PBF operate with a single 3.3V supply?
Yes, the LTC2207CUK#PBF operates from a single 3.3V analog supply (VDD) and supports independent digital output voltage (OVDD) from 0.5V to 3.6V. This allows direct interfacing with 1.8V, 2.5V, or 3.3V logic families without external level shifters. Power dissipation is 900mW at 105Msps, requiring proper thermal management via the exposed pad (Pin 49) soldered to PCB ground.
What is the purpose of the RAND pin on the LTC2207CUK#PBF?
The RAND pin on the LTC2207CUK#PBF enables digital output randomization: when asserted high, bits D1–D15 are XORed with D0 (LSB), reducing deterministic spectral components caused by repetitive digital switching patterns. This minimizes digital feedthrough into sensitive analog sections, improving SFDR in systems with tight EMI requirements - a feature confirmed in the datasheet's "Optional Data Output Randomizer" section.
