THS4561 Low-Power, High Supply Range, 60-MHz, Fully Differential Amplifier

differential output required by precision analog-to-

1 Features

digital converters (ADCs). Designed for a very low,

8-Hz, 1/f voltage noise corner and low, 130-dB total

harmonic distortion (THD) while consuming only a

775-µA quiescent current, the THS4561 is well suited

for power-sensitive data acquisition (DAQ) systems

where high performance is required with the best

signal-to-noise ratio (SNR) and spurious-free dynamic

range (SFDR) through the amplifier and ADC

combination.

•

Bandwidth: 60 MHz (G = 1 V/V)

Slew Rate: 230 V/µs

Gain Bandwidth Product: 68 MHz

Voltage Noise:

– 1/f Voltage Noise Corner: 8 Hz

– Broadband Noise (≥ 500 Hz): 4 nV/√ Hz

Input Offset: ±250 µV (Maximum)

– Drift: ±4 µV/°C (Maximum)

Supply Operating Range: 2.85 V to 12.6 V

Supply Current: 775 µA

Negative Rail Input (NRI)

Rail-to-Rail Output (RRO)

Very Low Harmonic Distortion:

– HD2: –117 dBc at 2 V_PP, 100 kHz

– HD3: –124 dBc at 2 V_PP, 100 kHz

0.01% Settling (2-V Step): 90 ns

•

The THS4561 features the required negative rail input

when interfacing a DC-coupled, ground-centered,

source signal to a single-supply, differential-input

ADC. Low DC error and drift terms support the

emerging high-speed and high-resolution successive

approximation register (SAR) and delta-sigma (ΔΣ)

ADC input requirements. A 2.85-V to 12.6-V supply

range with a flexible output common-mode setting

with low headroom to the supplies supports a wide

range of ADC input and digital-to-analog converter

(DAC) output requirements.

•

2 Applications

•

16-bit to 20-bit, Differential, SAR and ΔΣ Drivers

Differential Active Filters

High Output Swing PCM Audio DAC Outputs

Medical Ultrasounds

Battery Testers

Power Analyzers

The THS4561 device is characterized for operation

from –40°C to +125°C.
