MAX1771CSA
The MAX1771 step-up switching controller provides
90% efficiency over a 30mA to 2A load. A unique current-limited pulse-frequency-modulation (PFM) control
scheme gives this device the benefits of pulse-widthmodulation (PWM) converters (high efficiency at heavy
loads), while using less than 110?A of supply current (vs.
2mA to 10mA for PWM converters).
This controller uses miniature external components. Its
high switching frequency (up to 300kHz) allows surface-mount magnetics of 5mm height and 9mm diameter. It accepts input voltages from 2V to 16.5V. The
output voltage is preset at 12V, or can be adjusted
using two resistors
MAX186 Low Power 8-Channel Serial 12-Bit ADC Maxim DIP-20 Package
MAX186DCWP
The MAX186 evaluation system (EV system) consists of
a MAX186 evaluation kit (EV kit) connected to a Maxim
80C32 microcontroller (?C) module. The unit connects
to an IBM-compatible personal computer running software provided with the MAX186 EV kit. Both boards
come fully assembled and tested.
Using the EV system, the MAX186 input multiplexer can
be software-configured in a variety of single-ended or differential modes with unipolar or bipolar input ranges. The
MAX186 can be evaluated with a VSS voltage of 0V or
-5V, selectable from the personal computer?s keyboard.
The EV system is also useful for evaluating the
MAX186?s shutdown feature. The MAX186 can be
operated in three states of readiness between conversions. There are provisions for monitoring the supply
current in the different shutdown states, and for varying
the delay between conversions
MAX189ACWE
The MAX187 evaluation system (EV system) consists of a
MAX187 evaluation kit (EV kit) board plus a Maxim
68HC16 microcontroller (?C) module. Both boards come
fully assembled and tested, and software is provided. The
unit connects to an IBM-compatible personal computer.
The EV system can function as a data acquisition system,
collecting samples from the MAX187, storing them in memory, and displaying the conversion results on the host computer. Conversions may be self-timed or synchronized to
an external timebase. Waveforms can be digitized and displayed graphically versus time.
MAX191ACWG
The MAX191 is a monolithic, CMOS, 12-bit analog-todigital converter (ADC) featuring differential inputs,
track/hold (T/H), internal voltage reference, internal or
external clock, and parallel or serial ?P interface. The
MAX191 has a 7.5?s conversion time, a 2?s acquisition
time, and a guaranteed 100ksps sample rate.
The MAX191 operates from a single 5V supply or from
dual ?5V supplies, allowing ground-referenced bipolar
input signals. The device features a logic power-down
input, which reduces the 3mA VDD supply current to
50?A max, including the internal-reference current.
MAX202CSE
MAX200-MAX209, MAX211, and MAX213 are a family
of RS-232 and V.28 transceivers with integrated charge
pump circuitry for single 5V supply operation.
The drivers maintain the ?5V EIA/TIA-232E output signal
levels at data rates in excess of 120kbps when loaded in
accordance with the EIA/TIA-232E specification.
The MAX211 and MAX213 are available in a 28-pin, wide
small-outline (SO) package and a 28-pin shrink smalloutline (SSOP) package, which occupies only 40% of the
area of the SO. The MAX207 is available in a 24-pin SO
package and a 24-pin SSOP. The MAX203 and MAX205
use no external components and are recommended for
applications with limited circuit board space

MAX202ECSE+T
The MAX202E-MAX213E, MAX232E, and MAX241E are a
family of RS-232 and V.28 transceivers with high ?15kV
ESD HBM protection and integrated charge pump circuitry for single 5V supply operation. The various combinations of features are outlined in the Selector Guide. The
drivers and receivers for all ten devices meet all EIA/TIA232E and CCITT V.28 specifications at data rates up to
120kbps when loaded.
The MAX211E/MAX213E/MAX241E are available in 28-
pin SO and SSOP packages. The MAX202E/MAX232E
come in 16-pin TSSOP, narrow SO, wide SO, and DIP
packages. The MAX203E comes in a 20-pin DIP/SO
package, and needs no external charge-pump capacitors. The MAX205E comes in a 24-pin wide DIP package, and also eliminates external charge-pump
capacitors.

MAX218EAP
The MAX218 RS-232 transceiver is intended for batterypowered EIA/TIA-232E and V.28/V.24 communications
interfaces that need two drivers and two receivers with
minimum power consumption. It provides a wide 1.8V
to 4.25V operating voltage range while maintaining
true RS-232 and EIA/TIA-562 voltage levels. The
MAX218 runs from two alkaline, NiCd, or NiMH cells
without any form of voltage regulator.
A shutdown mode reduces current consumption to
1?A, extending battery life in portable systems. While
shut down, all receivers can remain active or can be
disabled under logic control, permitting a system incorporating the CMOS MAX218 to monitor external
devices while in low-power shutdown mode.
