Frequently Asked Questions
How many channels does the LTC2348CLX-18#PBF sample simultaneously and at what resolution and throughput?
The LTC2348CLX-18#PBF samples 8 differential channels simultaneously at 18-bit resolution with up to 200 ksps per channel. Simultaneous sampling eliminates phase skew between channels, which is critical for power analysis, motor control feedback, and multi-axis sensor fusion where the timing relationship between all 8 inputs must be preserved within a single conversion cycle.
What does the SoftSpan feature offer for the LTC2348CLX-18#PBF differential input configuration?
SoftSpan allows each of the 8 channels to be independently programmed to one of several differential input voltage ranges, including ±10.24 V, 0 V to 10.24 V, and smaller spans, all through serial configuration without hardware changes. This eliminates the need for external attenuators or range-switching relays when connecting multiple sensors with different output spans to the same 18-bit ADC, reducing BOM complexity and board area.
What package does the LTC2348CLX-18#PBF use and what are the key PCB layout considerations?
The LTC2348CLX-18#PBF is housed in a 48-pin LQFP (S-PQFP-G48) package, which is a standard quad flat package with an exposed lead frame that facilitates solder joint inspection. PCB layout should place decoupling capacitors within 1 mm of each VCC pin, keep analog and digital ground planes separate beneath the device, and route the LVDS output lines as matched-impedance differential pairs, typically 100 ohm differential, to maintain signal integrity at 200 ksps data rates.
When is the LTC2348CLX-18#PBF preferred over a 16-bit octal ADC in an industrial data acquisition design?
The LTC2348CLX-18#PBF's 18-bit resolution provides a full-scale dynamic range of approximately 262,144 counts versus 65,536 counts for a 16-bit device, a 4x improvement that matters in applications requiring measurement of small signal variations superimposed on large common-mode offsets or DC levels. For precision strain gauge bridges, high-resolution power quality monitoring, and scientific spectroscopy, the extra 2 bits reduce quantization noise by 12 dB, justifying the LTC2348CLX-18#PBF over 16-bit alternatives.
