12-Bit, Multichannel ADCs/DACs with FIFO,  
Temperature Sensing, and GPIO Ports  
General Description  
Features  
The MAX1220–MAX1223/MAX1257/MAX1258 integrate a  
12-bit, multichannel, analog-to-digital converter (ADC),  
and a 12-bit, octal, digital-to-analog converter (DAC) in a  
single IC. These devices also include a temperature sen-  
sor and configurable general-purpose I/O ports (GPIOs)  
with a 25MHz SPI™-/QSPI™-/MICROWIRE™-compatible  
serial interface. The ADC is available in 8/12/16 input-  
channel versions. The octal DAC outputs settle within  
2.0µs and the ADC has a 300ksps conversion rate.  
♦ 12-Bit, 300ksps ADC  
Analog Multiplexer with True-Differential  
Track/Hold (T/H)  
16 Single-Ended Channels or 8 Differential  
Channels (Unipolar or Bipolar)  
12 Single-Ended Channels or 6 Differential

8 Single-Ended Channels or 4 Differential  
Channels (Unipolar or Bipolar)  
Excellent Accuracy: 0ꢀ. ꢁSB ꢂIꢁ, 0ꢀ. ꢁSB DIꢁ  
All devices include an internal reference (2.5V or  
4.096V) for both the ADC and DAC. Programmable ref-  
erence modes allow the use of an internal reference, an  
external reference, or a combination of both. Features  
such as an internal 1°C accurate temperature sensor,  
FIFO, scan modes, programmable internal or external  
clock modes, data averaging, and AutoShutdown™  
allow users to minimize power consumption and proces-  
sor requirements. The low glitch energy (4nV•s) and low  
digital feedthrough (0.5nV•s) of the integrated octal  
DACs make these devices ideal for digital control of  
fast-response closed-loop systems.  
♦ 12-Bit, Octal, 2µs Settling DAC  
Ultra-ꢁow Glitch Energy (4nV•s)  
Power-Up Options from Zero Scale or Full Scale

♦ On-Chip FꢂFO Capable of Storing 16 ADC

♦ On-Chip Channel-Scan Mode and ꢂnternal  
The devices are guaranteed to operate with a supply volt-  
age from +2.7V to +3.6V (MAX1221/MAX1223/MAX1257)  
and from +4.75V to +5.25V (MAX1220/MAX1222/  
MAX1258). These devices consume 2.5mA at 300ksps  
throughput, only 22µA at 1ksp throughput, and under  
0.2µA in the shutdown mode. The MAX1257/MAX1258  
feature 12 GPIOs, while the MAX1220/MAX1221 offer 4  
GPIOs that can be configured as inputs or outputs.  
The MAX1220–MAX1223 are available in 36-pin thin  
QFN packages. The MAX1257/MAX1258 are available  
in 48-pin thin QFN packages. All devices are specified  
over the -40°C to +85°C temperature range.
