LTC1408CUH#PBF

Analog To Digital Converters (ADC) Overview

The LTC1408CUH#PBF is a 14-bit, 600ksps analog-to-digital converter (ADC) featuring six simultaneously sampled differential inputs. It operates from a single 3V supply, drawing 5mA in active mode and consuming only 6µW in Sleep shutdown mode. The device integrates a 2.5V internal bandgap reference and accepts 0V to 2.5V unipolar or ±1.25V bipolar differential input ranges. Data is output via a 3-wire serial interface over 96 clocks. Packaged in a compact 32-pin 5mm × 5mm QFN, it supports multiphase power measurement and motor control applications.

Analog To Digital Converters (ADC) Feature Summary

Six simultaneous sampling differential inputs with 100ksps throughput per channel
Low power consumption: 15mW active, 3.3mW Nap mode, 6µW Sleep mode
90dB common mode rejection ratio for noise elimination
Internal 2.5V reference with external overdrive capability

Analog To Digital Converters (ADC) Applications

Multiphase power measurement
Multiphase motor control
Data acquisition systems
Uninterruptable power supplies

Analog To Digital Converters (ADC) Procurement Notes

Verify the #PBF suffix confirms lead-free manufacturing status compliant with RoHS standards. Confirm the CUH suffix indicates the commercial temperature range of 0°C to 70°C. Ensure the QFN-32 package footprint matches the PCB layout requirements, specifically noting the exposed ground pad connection.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous multi-channel sampling is required at 600ksps total rate. Choose the bipolar input configuration by setting the BIP pin high for ±1.25V ranges, or low for 0V to 2.5V unipolar signals. Consider the 39ns acquisition time if driving high source impedance circuits without buffering.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1408 family of 14-bit ADCs. The 'C' designation specifies the commercial operating temperature range, while 'UH' identifies the specific 32-pin plastic QFN package variant. The '#PBF' marking denotes a lead-free finish compatible with standard surface mount assembly processes.
