Description for the LMH5485-SEP

The LMH5485-SEP is a radiation tolerant, low-power, voltage-feedback, fully differential amplifier (FDA). This part is able to achieve a high gain bandwidth product (GBWP) of 850-MHz, allowing it to maintain excellent distortion performance over a wide range of frequencies as shown in the following figure. This wide bandwidth range is also achieved with a relatively low power consumption of 10.1-mA and broadband voltage noise of 2.4nV/√Hz. This combination of power consumption, bandwidth and noise allows the LMH5485-SEP to be well suited for power sensitive data acquisition systems with frequencies >10 MHz that require both the best signal-to-noise ratio (SNR) and spurious-free dynamic range (SFDR).

The LMH5485-SEP features the negative-rail input required when interfacing with a DC-coupled, ground-centered, source signal. This negative-rail input, with a rail-to-rail output, allows for easy interface between single-ended, ground-referenced, bipolar signal sources and a wide variety of successive approximation register (SAR), delta-sigma (ΔΣ), or pipeline ADCs using only a single 2.7 V to 5.4 V power supply. This device also features a low offset voltage drift of ±0.5 µV/°C, allowing it to maintain excellent DC performance over it’s wide temperature range of –55°C to +125°C.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
