The ADA4841-1 is a unity gain stable, low noise and distortion, rail-to-rail output amplifier that has a quiescent current of 1.5 mA maximum. In spite of its low power consumption, this amplifier offers low wideband voltage noise performance of 2.1 nV/√Hz and 1.4 pA/√Hz current noise, along with excellent spurious-free dynamic range (SFDR) of −105 dBc at 100 kHz. To maintain a low noise environment at lower frequencies, the amplifier has low 1/f noise of 7 nV/√Hz and 13 pA/√Hz at 10 Hz.

The ADA4841-1 output can swing to less than 50 mV of either rail. The input common-mode voltage range extends down to the negative supply. The ADA4841-1 can drive up to 10 pF of capacitive load with minimal peaking.

The ADA4841-1 provides the performance required to efficiently support emerging 16-bit to 18-bit ADCs and is ideal for portable instrumentation, high channel count, industrial measurement, and medical applications. The ADA4841-1 is ideally suited to drive the AD7685/AD7686, 16-bit PulSAR ADCs.

The ADA4841-1 package features RoHS compliant lead finishes. The amplifier is rated to work over the industrial temperature range (−40°C to +125°C).

Applications

  • Low power, low noise signal processing
  • Battery-powered instrumentation
  • 16-bit PulSAR® ADC drivers

AD7761 Evaluation Board

AD7761 Evaluation Board

Features and Benefits

  • Full featured evaluation board for the AD7761
  • PC control in conjunction with the SDP-H1 system demonstration platform (EVAL-SDP-CH1Z)
  • PC software control and data analysis
  • Time and frequency domain
  • Standalone hardware capability

Product Detail

The EVAL-AD7761FMCZ evaluation kit features the AD7761 16-bit, 256 kSPS, analog-to-digital converter (ADC). A 7 V to 9 V external bench top supply is regulated to 5 V and 3.3 V to supply the AD7761 and support components. The EVAL-AD7761FMCZ board connects to the USB port of the PC via a connection to the EVAL-SDP-CH1Z motherboard.

The AD7761 evaluation software fully configures the AD7761 device register functionality and provides dc and ac time domain analysis in the form of waveform graphs, histograms, and associated noise analysis for ADC performance evaluation.

The EVAL-AD7761FMCZ is an evaluation board that allows the user to evaluate the features of the ADC. The user PC software executable controls the AD7761 over a USB cable through the EVAL-SDP-CH1Z system demonstration platform (SDP).

Full specifications for the AD7761 are available in the product data sheet, which should be consulted in conjunction with this user guide when working with the evaluation board.
