Frequently Asked Questions
What sample rate and resolution does LTC2165IUK#PBF achieve, and how does that benefit wideband signal capture?
The LTC2165IUK#PBF samples at 125 Msps with 16-bit resolution, providing a dynamic range that supports wideband signal capture across a 0 to 62.5 MHz Nyquist band. This combination enables accurate digitization of complex modulated signals in communications and radar applications without significant loss of spectral fidelity.
Which supply voltage does LTC2165IUK#PBF require, and what does that mean for system power budgets in portable instruments?
LTC2165IUK#PBF operates from a 1.8 V supply, which significantly lowers power consumption compared to 3.3 V ADCs of similar speed. In portable or rack-mount instruments with tight thermal budgets, this 1.8 V core supply reduces heat dissipation and allows designers to allocate more headroom for analog front-end circuitry across 2 input channels.
How many analog input channels does LTC2165IUK#PBF provide, and what is the supported analog input voltage range?
The device provides 2 analog input channels, each supporting a differential input voltage range of -2 V to +2 V (4 V peak-to-peak). This dual-channel capability allows simultaneous digitization of two independent signals, making it efficient for I/Q demodulation paths in software-defined radio designs.
What package does LTC2165IUK#PBF use, and how does its footprint affect PCB layout in high-frequency designs?
LTC2165IUK#PBF is housed in a 64-lead QFN (Quad Flat No-Lead) package. The exposed pad and compact body reduce parasitic inductance on supply pins, which is critical when routing 125 Msps clock and data lines. The QFN footprint typically measures under 9 mm × 9 mm, helping minimize board area in dense high-speed designs.
When is LTC2165IUK#PBF a suitable alternative to lower-speed 16-bit ADCs in test and measurement equipment?
LTC2165IUK#PBF is the better choice when the application requires capturing signals above 10 MHz bandwidth with 16-bit precision, such as in oscilloscope front-ends or spectrum analyzers sampling at 125 Msps. Lower-speed ADCs running at 10 Msps or 20 Msps would alias these high-frequency components, whereas LTC2165 handles them without degrading dynamic range.
