Howdy.

I'm in the market for an ADC.=20

- Definitely want I2C as the device already has several devices on the 'bus=
' and we have good, stable I2C code (this is an ARM device)
- 12-bits (or at least 10 'real' bits) would be preferred
- Power consumption well below 1mA when converting
- A standby/shutdown mode that has virtually no quiescent current
- Small (< 10 mm^2 is preferable)
- Around a buck in quantity 250
- Neither sampling latency (I2C sees to that) or maximum samples per second=
 are terribly important -- 1Hz updates would be just fine

The MCP3221 scores well (I2C, comes in a variety of addresses, is 12-bit(-i=
sh), <250uA current, <1uA standby, SOT23-5, ~$1.40). And I've had decent lu=
ck with the cost-features-reliability trifecta with Microchip in the past.

ny comments?=20

Any other recommendations?

TIA.
