MAX1415/MAX1416

16-Bit, Low-Power, 2-Channel,

Sigma-Delta ADCs

General Description

Beneﬁts and Features

● Improve Measurement Quality with Excellent DC

The MAX1415/MAX1416 low-power, 2-channel, serial-

output analog-to-digital converters (ADCs) use a sigma-

delta modulator with a digital filter to achieve 16-bit

resolution with no missing codes. These ADCs are

pin-compatible upgrades to the MX7705/AD7705. The

MAX1415/MAX1416 feature an internal oscillator (1MHz

or 2.4576MHz), an on-chip input buffer, and a program-

mable gain amplifier (PGA). The devices offer an SPI-/

Accuracy

• 16-Bit Sigma-Delta ADC with Two Fully-Differential

Input Channels

• 0.0015% INL (max) with No Missing Codes

● Minimize Power Consumption with Low-Power

Dissipation

• 1.2mW (max) 3V supply

•ꢀ 2μAꢀ(typ)ꢀPower-DownꢀCurrent

QSPI™-/MICROWIRE -compatible serial interface.

The MAX1415/MAX1416 are available in 16-pin PDIP,

SO, and TSSOP packages.

● Lower System Cost with Integrated Functionality

• PGA with 1 to 128 Programmable Gain

• Optional Input Buffers

Applications

● Industrial Instruments

• > 98dB 50Hz/60Hz Rejection

● Increase System Accuracy with Built-in Self

Calibration

● Weigh Scales

● Strain-Gauge Measurements

● Loop-Powered Systems

● Flow and Gas Meters

● Medical Instrumentation

● Pressure Transducers

● Thermocouple Measurements

● RTD Measurements

• On-Demand Offset and Gain Self-Calibration and

System Calibration

• User-Programmable Offset and Gain Registers

● Flexible Single-Supply Options

• 2.7V to 3.6V (MAX1415)

• 4.75V to 5.25V (MAX1416)

Ordering Information continued at end of data sheet.

● Pin Compatible Upgrades for MX7705/AD7705
