General Description

The MAX1179/MAX1187/MAX1189 16-bit, low-power,
successive-approximation analog-to-digital converters
(ADCs) feature automatic power-down, a factory-
trimmed internal clock, and a 16-bit wide parallel inter-
face. The devices operate from a single +4.75V to
+5.25V analog supply and feature a separate digital
supply input for direct interface with +2.7V to +5.25V
digital logic.
The MAX1179 accepts a bipolar input voltage range of
±5V. The MAX1187 accepts an analog input voltage
range from 0 to +10V, while the MAX1189 accepts a
bipolar analog input voltage range of ±10V. All devices
consume only 23mW at a sampling rate of 135ksps
when using an external reference and 29mW when
using the internal +4.096V reference. AutoShutdown™
reduces supply current to 0.4mA at 10ksps. The
MAX1179/MAX1187/MAX1189 are ideal for high-perfor-
mance, battery-powered data-acquisition applications.
Excellent AC performance (THD = -100dB) and DC
accuracy (±2LSB INL) make the MAX1179/MAX1187/
MAX1189 ideal for industrial process control, instrumen-
tation, and medical applications.
The MAX1179/MAX1187/MAX1189 are available in a
28-pin TSSOP package and are fully specified over the
-40°C to +85°C extended temperature range and the
0°C to +70°C commercial temperature range.

Detailed Description
Converter Operation

The MAX1179/MAX1187/MAX1189 use a successive-
approximation (SAR) conversion technique with an
inherent track-and-hold (T/H) stage to convert an ana-
log input into a 16-bit digital output. Parallel outputs
provide a high-speed interface to microprocessors
(µPs). The Functional Diagramat the end of the data
sheet shows a simplified internal architecture of the
MAX1179/MAX1187/MAX1189. Figure 3 shows a typical
application circuit for the MAX1179/MAX1187/MAX1189.
Analog Input
Input Scaler

The MAX1179/MAX1187/MAX1189 have an input scaler
which allows conversion of true bipolar input voltages
and input voltages greater than the power supply, while
operating from a single +5V analog supply. The input
scaler attenuates and shifts the analog input to match
the input range of the internal DAC. The MAX1179 input
voltage range is ±5V, while the MAX1189 input voltage
range is ±10V. The MAX1187 has a unipolar input volt-
age range of 0 to +10V. Figure 4 shows the equivalent
input circuit of the MAX1179/MAX1187/MAX1189. This
circuit limits the current going into or out of AIN to less
than 1.8mA.

Track and Hold (T/H)

In track mode, the internal hold capacitor acquires the
analog signal (see Figure 4). In hold mode, the T/H
switches open and the capacitive DAC samples the
analog input. During the acquisition, the analog input
(AIN) charges capacitor CHOLD. The acquisition ends
on the second falling edge of CS. At this instant, the
T/H switches open. The retained charge on CHOLDrep-
resents a sample of the input. In hold mode, the capac-
itive DAC adjusts during the remainder of the
conversion time to restore node T/H OUT to zero within
the limits of a 16-bit resolution. Force CSlow to put
valid data on the bus after conversion is complete.
Power-Down Modes

Select standby mode or shutdown mode with R/Cduring
the second falling edge of CS(see SelectingStandby or
Shutdown Modesection). The MAX1179/MAX1187/
MAX1189 automatically enter either standby mode (ref-
erence and buffer on) or shutdown (reference and buffer
off) after each conversion depending on the status of
R/Cduring the second falling edge of CS.
Internal Clock

The MAX1179/MAX1187/MAX1189 generate an internal
conversion clock to free the microprocessor from the bur-
den of running the SAR conversion clock. Total conver-
sion time after entering hold mode (second falling edge of
CS) to end-of-conversion (EOC) falling is 4.7µs (max).
Applications Information
Starting a Conversion
and R/Ccontrol acquisition and conversion in the
MAX1179/MAX1187/MAX1189 (see Figure 2). The first
falling edge of CSpowers up the device and puts it in
acquire mode if R/Cis low. The convert start (CS) is
ignored if R/Cis high. The MAX1179/MAX1187/
MAX1189 need at least 12ms (CREFADJ= 0.1µF, CREF
= 10µF) for the internal reference to wake up and settle
before starting the conversion, if powering up from
shutdown. Reset the MAX1179/MAX1187/ MAX1189 by
toggling RESET with CShigh. The next falling edge ofbegins acquisition.
Selecting Standby or Shutdown Mode

The MAX1179/MAX1187/MAX1189 have a selectable
standby or low-power shutdown mode. In standby
mode, the ADC’s internal reference and reference
buffer do not power down between conversions, elimi-
nating the need to wait for the reference to power up
before performing the next conversion. Shutdown mode
powers down the reference and reference buffer after
