Key highlights
The Texas Instruments LMH5485-SEP is a radiation-tolerant, low-power, voltage-feedback, fully differential amplifier (FDA).
It 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 an 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.
The 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).
Applications
- Low-power, high-performance ADC driver: SAR, ΔΣ, and pipeline
- Differential DAC output driver
- Command and data handling
- Launch vehicle systems
- Space imaging systems:
- Optical imaging payload
- Radar imaging payload
- Thermal imaging cameras
