General Description
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.
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 20A 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.
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.
The MAX1134/MAX1135 are available in a 20-pin SSOP
package and are fully specified over the -40°C to
+85°C temperature range.
