 | | Fully integrated 46 dB (200 V/V) amplifier array; no off-chip |
| | capacitors required.
|
| | Low input-referred noise: 2 microvolts RMS.
|
| | Fully differential architecture from input to output for maximum |
| | rejection of interference.
|
| | Low power operation: 1.7 - 2.6 mW per channel.
|
| | On-chip high-speed analog MUX allows many amplifiers to |
| | share one A/D converter.
|
| | Lower cutoff frequency below 0.1 Hz allows monitoring of very |
| | low frequency signals.
|
| | True zero gain at DC rejects large electrode offset voltages.
|
| | Upper cutoff frequency of all amplifiers set by two external |
| | resistors; tunable from 10 Hz to 10 kHz.
|
| | Third-order Butterworth low-pass filter at upper cutoff frequency |
| | for 60 dB/decade roll-off.
