16-Bit ADCs, 150ksps, 3.3V Single Supply

General Description

Features

The MAX1134/MAX1135 are 150ksps, 16-bit ADCs.

These serially interfaced ADCs connect directly to SPI™,

QSPI™, and MICROWIRE™ devices without external

logic. They combine an input scaling network, internal

track/hold (T/H), clock, and three general-purpose digital

output pins (for external multiplexer or PGA control) in a

20-pin SSOP package. The excellent dynamic perfor-

mance (THD ≥ 90dB), high speed (150ksps in bipolar

mode), and low power (8.0mA) of these ADCs make

them ideal for applications such as industrial process

control, instrumentation, and medical applications.

ꢀ Internal or External Clock

ꢀ SPI/QSPI/MICROWIRE TMS320-Compatible Serial

Interface

ꢀ Three User-Programmable Logic Outputs

The MAX1134 accepts input signals of 0 to +6V (unipo-

lar) or 6V (bipolar), while the MAX1135 accepts input

signals of 0 to +2.048V (unipolar) or 2.048V (bipolar).

Operating from a single 3.135V to 3.465V analog and

digital supply, power-down modes reduce current con-

sumption to 0.15mA at 10ksps and further reduce sup-

ply current to less than 20µA at slower data rates.

A serial strobe output (SSTRB) allows direct connection

to the TMS320 family digital-signal processors. The

MAX1134/MAX1135 user can select either the internal

clock or an external serial-interface clock for the ADC to

perform analog-to-digital conversions.

ꢀ Small 20-Pin SSOP Package

Ordering Information

The MAX1134/MAX1135 feature internal calibration cir-

cuitry to correct linearity and offset errors. On-demand

calibration allows the user to optimize performance.

Three user-programmable logic outputs are provided

for the control of an 8-channel mux or PGA.
