DESCRIPTION
24-Bit High Speed
Differential Δ∑ ADC with
Selectable Speed/Resolution
The LTC2440 is a high speed 24-bit No Latency Δ∑TM
ADC with 5ppm INL and 5μV offset. It uses proprietary
delta-sigma architecture enabling variable speed and reso-
lution with no latency. Ten speed/resolution combinations
(6.9Hz/200nVRMS to 3.5kHz/25μVRMS) are programmed
through a simple serial interface. Alternatively, by tying a
single pin HIGH or LOW, a fast (880Hz/2μVRMS) or ultralow
noise (6.9Hz, 200nVRMS, 50/60Hz rejection) speed/reso-
lution combination can be easily selected. The accuracy
(offset, full-scale, linearity, drift) and power dissipation
are independent of the speed selected. Since there is no
latency, a speed/resolution change may be made between
conversions with no degradation in performance.
Following each conversion cycle, the LTC2440 automati-
cally enters a low power sleep state. Power dissipation
may be reduced by increasing the duration of this sleep
state. For example, running at the 3.5kHz conversion speed
but reading data at a 100Hz rate draws 240μA average
current (1.1mW) while reading data at a 7Hz output rate
draws only 25μA (125μW).The LTC2440 communicates
through a exible 3-wire or 4-wire digital interface that is
compatible with the LTC2410 and is available in a narrow
16-lead SSOP package.
