8-/4-/2-Channel, 12-Bit, Simultaneous-Sampling ADCs with ±10V, ±5V, and 0 to +5V Analog Input Ranges

Product Details

The MAX1304–MAX1306/MAX1308–MAX1310/MAX1312–MAX1314 12-bit, analog-to-digital converters (ADCs) offer eight, four, or two independent input channels. Independent track-and-hold (T/H) circuitry provides simultaneous sampling for each channel. The MAX1304/MAX1305/MAX1306 provide a 0 to +5V input range with ±6V fault-tolerant inputs. The MAX1308/MAX1309/MAX1310 provide a ±5V input range with ±16.5V fault-tolerant inputs. The MAX1312/MAX1313/MAX1314 have a ±10V input range with ±16.5V fault-tolerant inputs. These ADCs convert two channels in 0.9µs, and up to eight channels in 1.98µs, with an 8-channel throughput of 456ksps per channel. Other features include a 20MHz T/H input bandwidth, internal clock, internal (+2.5V) or external (+2.0V to +3.0V) reference, and power-saving modes.

A 20MHz, 12-bit, bidirectional parallel data bus provides the conversion results and accepts digital inputs that activate each channel individually.

All devices operate from a +4.75V to +5.25V analog supply and a +2.7V to +5.25V digital supply and consume 57mA total supply current when fully operational.

Each device is available in a 48-pin 7mm x 7mm LQFP package and operates over the extended -40°C to +85°C temperature range.

Description

The MAX1308 evaluation system (EV system) is a complete 8-channel, 12-bit, data-acquisition system. The MAX1308 EV system (MAX1308EVB16) consists of a MAX1308 evaluation kit (EV kit), Maxim 68HC16MOD-16WIDE microcontroller (µC) module, and USBTO232. Order the EV kit (MAX1308EVKIT) separately if the user has a parallel bus controller or if the 68HC16MOD-16WIDE µC module has already been purchased.

The MAX1308 EV kit can be used to evaluate the MAX1308 with an external system clock. In this mode, the 68HC16MOD-16WIDE board cannot be used and the user must supply a parallel interface.

The EV kit comes with the MAX1308ECM installed. To evaluate the pin-compatible MAX1304ECM-MAX1307ECM and MAX1309ECM-MAX1315ECM, contact the factory for free samples.
