Product details

12-bit SAR, 188kSPS — what the throughput buys you

The AD7994BRUZ-1 is a 12-bit successive-approximation ADC sampling at 188 kSPS — fast enough to oversample a 10 kHz sensor signal 18× per cycle, leaving headroom for digital filtering without missing edges on a multiplexed four-channel scan. Single-ended input architecture with a 4:1 mux ahead of the S/H means each channel sees the full 12-bit resolution at the converter's native rate; the mux settles in one clock cycle, so the aggregate throughput across all four channels is 188 kSPS divided by the number of active channels.

2.7V to 5.5V single-supply — one rail, no level shifting

Both analog and digital supply pins run from the same 2.7V to 5.5V rail — no separate AVDD/DVDD domain, so a single 3.3V or 5V LDO feeds the whole part and the I2C bus voltage matches the digital supply without an external translator.

Active lifecycle, tube delivery — what to expect on the line

The tube ships 96 parts per tube per the standard 16-TSSOP tube quantity. If your pick-and-place feeder prefers tape, the AD7994BRUZ-0REEL is the same die in tape-and-reel — same footprint, same electricals, just the carrier format differs.

Frequently asked questions

Will AD7994BRUZ-1 drop into a board that was specified around AD7994BRUZ-0 without rewiring?

Yes — the AD7994BRUZ-0 and AD7994BRUZ-1 share the same pinout, 16-TSSOP footprint, single-ended 4-channel mux, I2C interface, and 188 kSPS throughput. The only difference is the I2C address; the AD7994BRUZ-1 responds to a different slave address, so the firmware must be updated to match. No board spin required.
