Linear Technology's LTC2338-18 is a low-noise, high-speed 18-bit successive approximation register (SAR) ADC with fully-differential inputs. Operating from a single 5 V supply, the LTC2338-18 has a ±10.24 V true-bipolar input range, making it ideal for high-voltage applications which require a wide dynamic range. The LTC2338-18 achieves ±4LSB INL maximum, no missing codes at 18-bits with 100 dB SNR.
The LTR4321 is a dual ideal-diode bridge controller that enables a Power-over-Ethernet (PoE) powered device (PD) to receive power in either voltage polarity from RJ-45 data pairs, spare pairs, or both. The LT4321 and eight N-channel MOSFETs replace the eight diodes in a passive PoE rectifier bridge. The LT4321 eases thermal design and increases delivered power.
