RHA2116
16-channel biopotential amplifier array
Introduced in 2010, the RHA2116 is an integrated,
low-power amplifier array from Intan Technologies. This
single-chip device contains 16 low-noise, low-power
amplifiers with programmable bandwidths suitable for
many bioinstrumentation monitoring and recording
applications. RHA2116 chips are packaged in standard
6 mm x 6 mm 40-pin QFN surface-mount packages.

RHA2116 Features
 | Fully integrated amplifier array; no off-chip capacitors required. | |
| Low input-referred noise: 2 microvolts RMS. | |
| Low power operation: 500 microwatts per channel. | |
| On-chip high-speed analog multiplexer allows many amplifiers | |
| to share one A/D converter. | ||
| Upper cutoff frequency of all amplifiers set by external resistors; | |
| adjustable from 10 Hz to 20 kHz | ||
| Lower cutoff frequency of all amplifiers set by external resistor; | |
| adjustable from 0.02 Hz to 1.0 kHz. | ||
| True zero gain at DC rejects electrode offset voltages. | |
| In situ electrode impedance measurement capability. | |
