Rainbow Electronics MAX1301 User Manual

General Description

The MAX1300/MAX1301 multirange, low-power, 16-bit,
successive-approximation, analog-to-digital converters
(ADCs) operate from a single +5V supply and achieve
throughput rates up to 115ksps. A separate digital sup­ply allows digital interfacing with 2.7V to 5.25V systems
using the SPI™-/QSPI™-/MICROWIRE™-compatible
serial interface. Partial power-down mode reduces the
supply current to 1.3mA (typ). Full power-down mode
reduces the power-supply current to 1µA (typ).

The MAX1300 provides eight (single-ended) or four
(true differential) analog input channels. The MAX1301
provides four (single-ended) or two (true differential)
analog input channels. Each analog input channel is
independently software programmable for seven sin­gle-ended input ranges (0 to +6V, -6V to 0, 0 to +12V,

-12V to 0, ±3V, ±6V, and ±12V), and three differential
input ranges (±6V, ±12V, ±24V).

An on-chip +4.096V reference offers a small convenient
ADC solution. The MAX1300/MAX1301 also accept an
external reference voltage between 3.800V and 4.136V.

The MAX1300 is available in a 24-pin TSSOP package
and the MAX1301 is available in a 20-pin TSSOP pack­age. Each device is specified for operation from -40°C
to +85°C.

Note 2: See definitions in the Parameter Definitions section at the end of the data sheet.
Note 3: Guaranteed by correlation with single-ended measurements.
Note 4: Not production tested. Guaranteed by design.
Note 5: To ensure external reference operation, V

REFCAP

must exceed (AV

DD1

- 0.1V). To ensure internal reference operation, V

REFCAP

must be below (AV

DD1

- 0.4V). Bypassing REFCAP with a 0.1µF or larger capacitor to AGND1 sets V

REFCAP

≈ 4.096V. The tran-

sition point between internal reference mode and external reference mode lies between the REFCAP buffer disable threshold
minimum and maximum values (Figures 17 and 18).

Note 6: The SCLK duty cycle can vary between 40% and 60%, as long as the t

and tCHtiming requirements are met.

Note 7: For partial power-down and full power-down modes, external clock mode was used for a burst of continuous samples.

Partial power-down or full power-down modes were entered thereafter. By using this method, the conversion rate was found
by averaging the number of conversions over the time starting from the first conversion to the end of the partial power-down
or full power-down modes.
