Introduction
The THS4521 is an ultra-low power, fully differential amplifier featuring rail-to-rail output and an input common-mode range that includes the negative supply rail. This amplifier is designed for low-power data acquisition systems and high-density applications where power dissipation is a critical parameter, and also delivers excellent performance in audio applications.
The THS4521 provides precise output common-mode control, enabling DC coupling when driving ADCs. This control capability, combined with an input common-mode range that extends below the negative supply rail and rail-to-rail output, allows straightforward interfacing between single-ended ground-referenced signal sources. In addition, the device is well suited for driving SAR and delta-sigma (ΔΣ) ADCs using only a single 2.5-V to 3.3-V supply and ground.
The THS4521 is characterized for operation over a temperature range of -55°C to 210°C.
Features
- Fully differential architecture
- Bandwidth: 40.7MHz (210°C)
- Slew rate: 353.5 V/μs (210°C)
- HD₂: -96dBc at 1kHz (1 VRMS; RL = 1 kΩ) (210°C)
- HD₃: -91.5 dBc at 1kHz (1 VRMS; RL = 1 kΩ) (210°C)
- Input voltage noise: 19.95 nV/√Hz (f = 100 kHz)
- Open-loop gain: 90 dB (typical) (210°C)
- NRI — negative rail input
- RRO — rail-to-rail output
- Output common-mode control (with low offset and low drift)
- Supply:
- Voltage: 2.5 V (±1.25 V) to 3.3 V (±1.65 V)
- Current: 1.4 mA per channel (at 3.3 V)
- Power-down: 10 μA (typical) (210°C)
Applications
- High-temperature environments for down-the-hole drilling
